Studies of the binding of different iron donors to human serum transferrin and isolation of iron-binding fragments from the N- and C-terminal regions of the protein. (1/4726)

1. Trypsin digestion of human serum transferrin partially saturated with iron(III)-nitrilotriacetate at pH 5.5 or pH 8.5 produces a carbohydrate-containing iron-binding fragment of mol.wt. 43000. 2. When iron(III) citrate, FeCl3, iron (III) ascorabate and (NH4)2SO4,FeSO4 are used as iron donors to saturate the protein partially, at pH8.5, proteolytic digestion yields a fragment of mol.wt. 36000 that lacks carbohydrate. 3. The two fragments differ in their antigenic structures, amino acid compositions and peptide 'maps'. 4. The fragment with mol.wt. 36000 was assigned to the N-terminal region of the protein and the other to the C-terminal region. 5. The distribution of iron in human serum transferrin partially saturated with various iron donors was examined by electrophoresis in urea/polyacrylamide gels and the two possible monoferric forms were unequivocally identified. 6. The site designated A on human serum transferrin [Harris (1977) Biochemistry 16, 560--564] was assigned to the C-terminal region of the protein and the B site to the N-terminal region. 7. The distribution of iron on transferrin in human plasma was determined.  (+info)

The structure of a glycopeptide (GP-II) isolated from Rhizopus saccharogenic amylase. (2/4726)

Mild alkaline treatment of glycopeptide (GP-II) resulted in the loss of 1 mole of serine and 5 moles of threonine per mole of GP-II, suggesting the presence of O-glycosyl bonds between 1 serine and 5 threonine residues and carbohydrate chains. Treatment of GP-II with alkaline borohydride released only disaccharide. Methylation studies of the carbohydrate moiety gave 2,3,4,6-tetra-O-methyl and 2,4,6-tri-O-methyl derivatives of mannose in a ratio of approximately 1:1. In addition, one step of Smith degradation resulted in the loss of about 6 residues of mannose per mole of GP-II. Moreover, alpha-mannosidase [EC] liberated about 6 residles of mannose per mole of GP-II. On the basis of these data, the structure of the carbohydrate moiety of GP-II was confirmed to be 3-O-alpha-mannosylmannose. The amino- and carboxyl-terminal amino acids of GP-II were determined to be threonine and serine, respectively. On reductive cleavage of N-proline bonds with metallic sodium in liquid ammonia, 2 moles of alanine per mole of GP-II were lost. From the compositions of three fragments isolated from the reductive cleavage products, the amino acid sequence of the peptide portion of GP-II was determined. Based on these data, a probable structure was proposed for GP-II.  (+info)

Isolation and characterization of two mouse L cell lines resistant to the toxic lectin ricin. (3/4726)

Two variant mouse L cell lines (termed CL 3 and CL 6) have been selected for resistant to ricin, a galactose-binding lectin with potent cytotoxic activity. The resistant lines exhibit a 50 to 70% decrease in ricin binding and a 300- to 500-fold increase in resistance to the toxic effects of ricin. Crude membrane preparations of CL 3 cells have increased sialic acid content (200% of control), while the galactose, mannose, and hexosamine content is within normal limits. Both the glycoproteins and glycolipids of CL 3 cells have increased sialic acid, with the GM3:lactosylceramide ratios for parent L and CL 3 cells being 0.29 and 1.5, respectively. In contrast, the membranes of CL 6 cells have a decrease in sialic acid, galactose, and hexosamine content with mannose being normal. Both cell lines have specific alterations in glycosyltransferase activities which can account for the observed membrane sugar changes. CL 3 cells have increased CMP-sialic acid:glycoprotein sialyltransferase and GM3 synthetase activities, while CL 6 cells have decrease UDP-GlcNAc:glycoproteinN-acetylglucosaminyltransferase and DPU-galactose:glycoprotein galactosyltransferase activities. The increased sialic acid content of CL 3 cells serves to mask ricin binding sites, since neuraminidase treatment of this cell line restores ricin binding to essentially normal levels. However, the fact that neuraminidase-treated CL 3 cells are still 45-fold resistant to ricin indicates that either a special class of productive ricin binding sites is not being exposed or that the cell line has a second mechanism for ricin resistance.  (+info)

A new sugar chain of the proteinase inhibitor from latex of Carica papaya. (4/4726)

The structure of a sugar chain of the proteinase inhibitor from the latex of Carica papaya was studied. Sugar chains liberated on hydrazinolysis were N-acetylated, and their reducing-end residues were tagged with 2-aminopyridine. One major sugar chain was detected on size-fractionation and reversed-phase HPLC analyses. The structure of the PA-sugar chain was determined by two-dimensional sugar mapping combined with sequential exoglycosidase digestion and partial acid hydrolysis, and by 750 MHz 1H-NMR spectroscopy. The structure found was Manalpha1-6(Manalpha1-3)Manalpha1-6(Manalpha1-3) (Xylbeta1-2)Manbeta1- 4GlcNAcbeta1-4(Fucalpha1-3)GlcNAc. This sugar chain represents a new plant-type sugar chain with five mannose residues.  (+info)

Prophenoloxidase-activating enzyme of the silkworm, Bombyx mori. Purification, characterization, and cDNA cloning. (5/4726)

Prophenoloxidase-activating enzyme (PPAE) was purified to homogeneity as judged by SDS-polyacrylamide gel electrophoresis from larval cuticles of the silkworm, Bombyx mori. The purified PPAE preparation was shown to be a mixture of the isozymes of PPAE (PPAE-I and PPAE-II), which were eluted at different retention times in reversed-phase high performance liquid chromatography. PPAE-I and PPAE-II seemed to be post translationally modified isozymes and/or allelic variants. Both PPAE isozymes were proteins composed of two polypeptides (heavy and light chains) that are linked by disulfide linkage(s) and glycosylated serine proteases. The results of cDNA cloning, peptide mapping, and amino acid sequencing of PPAE revealed that PPAE is synthesized as prepro-PPAE with 441 amino acid residues and is activated from pro-PPAE by cleavage of a peptide bond between Lys152 and Ile153. The homology search showed 36.9% identity of PPAE to easter, which is a serine protease involved in dorso-ventral pattern formation in the Drosophila embryo, and indicated the presence of two consecutive clip-like domains in the light chain. A single copy of the PPAE gene was suggested to be present in the silkworm genome. In the fifth instar larvae, PPAE transcripts were detected in the integument, hemocytes, and salivary glands but not in the fat body or mid gut. A polypeptide cross-reactive to mono-specific anti-PPAE/IgG was transiently detected in the extract of eggs between 1 and 3 h after they were laid.  (+info)

Paracellular glucose transport plays a minor role in the unanesthetized dog. (6/4726)

Traditionally, intestinal glucose absorption was thought to occur through active, carrier-mediated transport. However, proponents of paracellular transport have argued that previous experiments neglected effects of solvent drag coming from high local concentrations of glucose at the brush-border membrane. The purpose of this study was to evaluate glucose absorption in the awake dog under conditions that would maximize any contribution of paracellular transport. Jejunal Thiry-Vella loops were constructed in six female mongrel dogs. After surgical recovery, isotonic buffers containing L-glucose as the probe for paracellular permeability were given over 2-h periods by constant infusion pump. At physiological concentrations of D-glucose (1-50 mM), the fractional absorption of L-glucose was only 4-7% of total glucose absorption. Infusion of supraphysiological concentrations (150 mM) of D-glucose, D-maltose, or D-mannitol yielded low-fractional absorptions of L-glucose (2-5%), so too did complex or nonabsorbable carbohydrates. In all experiments, there was significant fractional water absorption (5-19%), a prerequisite for solvent drag. Therefore, with even up to high concentrations of luminal carbohydrates in the presence of significant water absorption, the relative contribution of paracellular glucose absorption remained low.  (+info)

Sugar- and nitrogen-dependent regulation of an Amanita muscaria phenylalanine ammonium lyase gene. (7/4726)

The cDNA of a key enzyme of secondary metabolism, phenylalanine ammonium lyase, was identified for an ectomycorrhizal fungus by differential screening of a mycorrhizal library. The gene was highly expressed in hyphae grown at low external monosaccharide concentrations, but its expression was 30-fold reduced at elevated concentrations. Gene repression was regulated by hexokinase.  (+info)

Lack of effect of carbohydrate depletion on some properties of human mast cell chymase. (8/4726)

Human chymase from vascular tissues was purified to homogeneity by heparin affinity and gel filtration chromatography. Treatment of human chymase with endoglycosidase F resulted in cleavage of the carbohydrate moiety yielding a deglycosylation product that did not lose its catalytic activity. This enzymatic deglycosylation product was enough to explore possibilities that N-glycan might modify some properties of human chymase. Substrate specificity, optimum pH and the elution profile from the heparin affinity gel were not affected by the deglycosylation. Only a slight but significant difference was observed in the Km value for conversion of angiotensin I to angiotensin II. Other kinetic constants such as kcat were not influenced. The kinetics of conversion of big endothelin-1 to endothelin-1(1-31) were not significantly affected. The deglycosylated human chymase was more susceptible to deactivation under alkaline pH and thermal stress. Even at physiological temperature and pH, the activity of glycosylated human chymase was more stable. From these results, it appears that the N-glycan of human chymase contributes to the stability of this enzyme but not to its functional properties.  (+info)

Carbohydrate synthesis is a sub-field of organic chemistry concerned specifically with the generation of natural and unnatural carbohydrate structures. This can include the synthesis of monosaccharide residues or structures containing more than one monosaccharide, known as oligosaccharides. Generally speaking, carbohydrates can be classified into two groups, simple sugars and complex carbohydrates. Simple sugars, also called monosaccharides, are carbohydrates which can not be converted into smaller sugars by hydrolysis. When two or more monosaccharide units are connected to one another via a glycoside linkage, complex carbohydrates are formed. Complex carbohydrates, according to the different number of monosaccharide units, can be classed into three groups, disaccharides, oligosaccharides, and polysaccharides. A disaccharide is formed from two monosaccharides. Oligosaccharides can be formed by a small number of monosaccharides linked together. Higher oligosaccharides are called polysaccharides. ...

Complex Carbohydrates, or starches, are composed of many simple sugars joined together by chemical bonds. These bonds can be linked in a serial chain, one after the other, as well as side to side, creating branches. Basically, the more chains and branches, the more complex the carbohydrate. The more complex a carbohydrate is, the more slowly it is broken down. Some carbohydrates are complex in a way that the body cannot digest them. These carbohydrates are a major component of fiber and generally pass through the digestive tract unabsorbed. In general, as long as complex carbohydrates are present in high fiber foods, the body breaks down complex carbohydrates into simple sugars more gradually, which leads to better blood sugar control. More and more research on heart disease, various forms of cancer, and diabetes indicates that complex carbohydrates including high fiber foods should form a major part of the diet. For example, the Dietary Approaches to Stop Hypertension, or DASH, diet focuses on ...
Human immunodeficiency virus (HIV) infection of T-cells begins when the viral envelope glycoprotein, gp120, binds to CD4 receptors on the target cell surface. Over the past several years, proteins isolated from various prokaryotes have been shown to inhibit HIV cell entry by binding to gp120 and thus blocking the association with CD4. Lectins that bind to high-mannose oligosaccharides on gp120 are an attractive class of antiviral agents. While several of these have been quite well characterized both structurally and biochemically, there remain many open questions regarding their mechanism of inhibition. Among the best studied is cyanovirin-N (CVN), which is currently under clinical study for use as a topical prophylactic. Large-scale molecular dynamics simulations have identified important structural features of this system that are difficult to resolve experimentally, and binding free energies of a diverse set of oligosaccharide targets computed from these structural ensembles give remarkable ...
Results showed that total bacterial numbers remained fairly constant throughout the diurnal period regardless of the diet fed. However, the number of viable bacteria decreased rapidly after feeding reaching its lowest level at 2 or 4 h post-feeding. Thereafter the viable population increased gradually, reaching its highest number at 16 h post-feeding. Changes in the major carbohydrate metabolizing groups within the bacterial population were, in general, not related to the theoretical pattern of ruminal fermentation for the primary carbohydrate components (soluble sugars, starch, pectin, hemicellulose and cellulose) in the diets fed. The most striking observation was that the soluble carbohydrate utilizing bacteria predominated at all times in both diets. Xylan and pectin degrading bacteria comprised about one half and one third of the population, respectively (slightly less on the high concentrate diet). These groups reached maximum representation between 8 and 12 h post-feeding. The ...

First, carbohydrates are the food category of sugars And the molecules that your body breaks down to make sugars Carbohydrates are simple or complex, depending on their structure This simple sugar or monosaccharide Glucose, fructose, and galactose are all simple sugars Connect the two together, and you get a disaccharide Lactose, maltose, or sucrose Complex carbohydrates, on the other hand Make three or more simple sugars bond together Complex carbohydrates consist of three to ten sugar bonds Polysaccharides Those that contain more than ten form a polysaccharide During the digestive process Your body breaks down complex carbohydrates Into monosaccharides ...
Carbohydrate is an organic compound that consists only of carbon, hydrogen and oxygen and has double the amount of carbon and oxygen. Carbohydrates contain sugars, starches, cellulose and other compounds found in living organisms. Carbohydrates most basic form is simple sugars or monosaccharide. There are three other chemical groupings: disaccharides, oligosaccharides and polysaccharides. Simple sugars can be combined into other carbohydrates for form more complex carbohydrates. Humans break down carbohydrates during the process of metabolism to release energy. Humans get carbohydrates from eating foods that contain it. Most carbohydrates are produced by plants during photosynthesis. In food, the term carbohydrate means any food that is particularly rich in starch ...
The carbohydrate and lipid composition of varagu millet has been determined. Starch was the major carbohydrate constituent ( - 72%) of the polished millet. Aqueous alcohol extraction of the millet furnished fructose, galactose, glucose, sucrose, raffinose and an unidentified component. Alkali extraction of the starch-free residue gave hemicelluloses A and B. Hemicellulose A contained glucose with small amounts of rhamnose, arabinose, xylose and mannose; whereas hemicellulose B was composed ofglucoseand galactose. The alkali-insoluble residue represented cellulose or fibre component as it was exclusively composed of glucose. Linoleic acid was the major fatty acid constituent of the free lipids, and palmitic acid was the major fatty acid of the bound lipids.. ...
Introduction. The Role of Carbohydrates Carbohydrates are a very large group of molecules that can be synthesised by plants. They are molecules which contain carbon, hydrogen and oxygen atoms. Usually there is a ratio of 2:1 of hydrogen to oxygen atoms in a carbohydrate molecule. Carbohydrates are very common constituents of plants. They make up to around 90% of the dry mass of plants. Carbohydrates are also an essential part of the animal diet and they are usually obtained directly or indirectly from plants. The functions of carbohydrates vary greatly. There are many different carbohydrates with different sizes and structures, all of which perform a different task in plants or animals. Functions range from being an energy store to providing structural support and strength. There are three types of carbohydrates; they are the monosaccharides, disaccharides and polysaccharides. This division is based on the fact that polysaccharides are non-sugars whereas monosaccharides are simple sugars and ...
It is a common belief that eating even low amounts of carbohydrates increases body weight, whether the carbs are from sugar, bread, fruits or vegetables. The reason for this misconception may be that eating carbohydrates raises insulin, which then lowers blood sugar. Low sugar increases appetite so a person ends up eating more. Considering this, some people advocate significant reduction of carbohydrates in their diet. But diets low in carbohydrates are likely to lack essential nutrients from plant foods, so people may not get enough vitamins, minerals and fiber. Athletes often follow a carbohydrate-loading diet, which involves increasing the amount of carbohydrates for several days before a high-intensity endurance athletic event.. Carbohydrates are one of the most important sources of energy for the human body. Foods containing carbohydrates cant be cut off a healthy diet because they provide fiber, sugars, and starches, which supply energy to the body in the form of glucose (blood sugar), ...

The mechanism was investigated using small oligosaccharides and a new column, PolyGLYCOPLEX. Some carbohydrates exhibited anomer separation, which made it possible to determine the orientation of the reducing end relative to the stationary phase. Amide sugars were consistently good contact regions. Relative to amide sugars, sialic acids and neutral hexoses were better contact regions at lower levels of organic solvents than at higher levels. HILIC readily resolved carbohydrates differing in residue composition and position of linkage. Complex carbohydrate mixtures could be resolved using ...
Get this from a library! Cell surface carbohydrate chemistry. [Robert E Harmon; American Chemical Society. Division of Carbohydrate Chemistry.;]
Plant foods such as vegetables, tubers, fruits, and functional plant parts store their carbohydrates in living cells that stay largely intact during cooking and are first breached during the digestive process. These fiber-walled living cells only allow for a maximum density of around 23% non-fibrous carbohydrate by mass, which explains why ancestral sources of carbohydrates such as fruits and vegetables have a relatively low-carbohydrate density compared to the most common sources of carbohydrate in the western diet (14).. Flour, sugar and processed plant foods dont have this cellular storage and contain a considerably higher percentage of carbohydrate than anything else we have been eating throughout our evolutionary history. These acellular carbohydrates are essentially already broken down through the production process and provide an evolutionary unprecedented high concentration of carbohydrates in the semifluid mass of partly digested food that pass from the stomach into the small ...
The amount of carbohydrate present in food that is actually utilized for energy. Dietary fiber is subtracted in the very beginning, if the food item contains ingredients such as sugar alcohol hydrogenated starch hydrolysate these are subtracted from the total carbohydrate count as well. Terms with similar meaning include usable carbs, utilizable carbohydrates, net carbs, net impact carbs, and net Atkins count.
Carbohydrates are made by plants and stored in their leaves, stems, roots, and fruits. Plant foods contain both simple and complex carbohydrates in various amounts. Fruits are often more than 90 percent carbohydrate, but most of their carbohydrates are the sweet-tasting simple forms of carbohydrate, such as glucose and fructose. Green and yellow vegetables store most of their calories as complex carbohydrates, but since they contain very few total calories the amount of complex carbohydrate they provide in the diet is small. Whole grains (rice, corn) and the whole grain flours (wheat, rye) and whole grain pastas (wheat, soba) made from them, tubers (potatoes, yams), legumes (beans, peas), and winter squashes (acorn, hubbard) contain large quantities of complex carbohydrates and thus are known as starches. Rice, corn, and other grains, and potatoes typically store about 80 percent of their calories in the form of complex carbohydrates. Beans, peas, and lentils are approximately 70 percent complex ...

There are plenty of myths circulating about carbohydrates, most saying that they should be avoided for anyone trying to lose or maintain a healthy weight. However, this is not the case. Carbohydrates should account for anywhere between 45 and 65% of macronutrients consumed in the diet. This means that carbohydrates are not to be avoided! Authors Ellie Whitney and Sharon Rolfes state that epidemiological studies find an inverse relationship between carbohydrate intake and body weight. Those with the highest carbohydrate intake have the lowest body weight and vice versa. Now, keep in mind that they are referring to the wholesome kind of carbs, whole-grain and unrefined. On the flip side, too much sugar (i.e. monosaccharides) added into the food is associated with the presence of more body fat. Sugar in this case is referring to refined carbs. Also, foods high in refined sugars are lacking in protein, vitamins, minerals, and fiber which whole-grain carbohydrates have. Thankfully, we can easily ...
Carbohydrates are organic compounds that encompass the food group known as that which most of us love to eat the most. Carbohydrates are sugars.

Carbohydrate Addiction.. There is no science behind the recommendation for the population to consume 55% of their diet as carbohydrates. This unscientific number was the result of the recommended intake of fat as a percentage of the food being reduced. So carbohydrates were utilised to fill the gap. That is all there is to it.. It is probably no accident that we like carbohydrates. It might be an evolutionary adaption. People have talked before about the addictive properties of carbohydrates. There are glucose sensors in the hepatic portal veins that are linked to the addiction centres in the brain with functional MRI.. In the early years of human evolution, carbohydrates were probably necessary for survival. In the summer and autumn months, fruits and other sources of sugar become available. These things are scarce at different times of the year in northern climates, such as in the UK.. So, eating to excess and then converting the carbohydrates into fat would be crucial to help the human-animal ...
Our group is interested in chemical glycobiology.. Total synthesis is combined with an enzymatic approach to prepare complex carbohydrates, glycopeptides and semi-synthetic glycoproteins. By using synthetic molecules structural details in protein-carbohydrate interactions are explored, which are relevant in infections, inflammation, cancer and aging. In addition to understand disease mechanisms, an ultimate aim in our projects is to develop glycomimetic inhibitors to block specific protein-carbohydrate interactions for instance to address the current problems with antimicrobial resistance in airway disease infections. We further apply synthetic glycopeptides and semi-synthetic glycoproteins to develop glycoproteomic tools for improved enrichment and characterization of glycan structural isomers of glycoproteins and for studies of new PTMs. Small differences in carbohydrate structure has an enormous impact on biological function, for instance in turning on or off an inflammatory pathway and makes ...
The sugar is listed under total carbohydrates. Total carbohydrates is composed of two parts fibers and sugar and some unspecified carbohydrates so that means 24 g = 4g fiber + 12 g sugar + 8 g some unspecified source. So the question says calories from a carbohydrate which is sugar alone hence 12/24 = 50% since only total carbohydrates generate the 160 calories and so we get 50% * 160 = 80 calories from sugar ...

The most important function of carbohydrates is to provide adequate energy to the animal. Dogs are able to convert certain carbohydrate sources into simple sugars that are easily absorbed. More complex carbohydrates must be broken down further by the body before they are able to be absorbed.. Carbohydrates are broken down in the small intestine into glucose molecules. Glucose is the common energy source that can be used by the majority of body cells. Glucose is required by the body to provide quick energy, and is also needed by the brain and nervous system for normal function. Glucose can be stored in the body for release later in the form of glycogen. If the animal eats too much and exercises too little, this stored glycogen will convert into fatty deposits in the body and cause obesity.. ...

Section 1: The effect of carbohydrate and fat on the N retention of the fasting rat. 1. Experiments are described on adult rats, which had been stabilised on a protein-containing or a protein-free diet and after a 24 hour fast received either water, glucose or olive oil. 2. Carbohydrate administration significantly reduced the urinary M output in both dietary groups. Fat administration decreased the urinary E output to a less significant degree. 3. The protein M content of the liver was significantly reduced after carbohydrate administration. Fat administration did not significantly reduce the protein 1 content of the liver. 4. It was concluded that the feeding of carbohydrate resulted in N retention in the body in tissues other than the liver.

All eukaryotic cells are covered in a dense layer of carbohydrates that are key to cell-cell communication, development, neurobiology and immune function. In addition, many human viruses interact with cell-surface carbohydrates as receptors on their host cells in order to initiate infection. Carbohydrate structures are expressed in tissue- and species-specific patterns, and the availability of the receptor carbohydrate influences viral tissue tropism and host range. Viruses also encounter carbohydrates in the extracellular matrix and the environment on their way from one host cell to another. Some of these extracellular glycans sequester viruses from cells and are part of innate immunity, while others can render viruses more infectious. In any case, the specificity and affinity of viral proteins for carbohydrates determines viral spread, transmission and pathogenesis. However, protein-carbohydrate interactions are less well understood than protein-protein or protein-nucleic acid interactions. ...
Carbohydrates are a common class of simple organic compouds. A carbohydrate is an aldehyde or a ketone that has additional hydroxyl groups. The simplest carbohydrates are called monosaccharides, which has the basic structure (C·H2O)n, where n is three or greater. Monosaccharides link together to form oligosaccharides and polysaccharides. Two monosaccharides link together to form a disaccharide ...
She continues by explaining, Total carbs also accounts for the grams of fiber in a product. Fiber is technically a carbohydrate (according to the chemistry), however, fiber is mostly non-nutritive, meaning, we dont digest and absorb the calories from fiber. Although we do not have the enzymes to break down fibers in our upper digestive system, the bacteria in our lower bowel do. This means that fiber technically yields calories, except they are usually good calories that provide nourishment to gut-lining cells and good bacteria and usually not associated with weight gain. Sugar alcohols should really be a category on their own since they can be partially digested but also tend to cause gut upset in many people.. To find the net carbs subtract fiber from total carbs, leaving only nutritive carbohydrates. Meaning, only the carbohydrates that are digested and absorbed into the bloodstream as simple sugars. Net carbs can only be calculated this way if fiber has been added into the total carbs. ...
Carbohydrates is a very common ingredient to most of the food we consume every day and it is also very important for our health. But currently, carbohydrate is being avoided by so many people for the weight loss reason. But they are missing out on one thing that carbohydrate should be avoided in those kinds of foods which are very rich in sugar and originally e comes in the junk food item. Those foods are really fattening but you should not leave carbohydrates completely because somehow we get energy from it in our everyday life. We have given a list of five items which are really very healthy in nature and also contain carbohydrates in them.. 1. Oatmeal ... The Molecular Immunology of Complex Carbohydrates [4191473] - During the past three decades, the sugar moiety of complex carbohydrates has been found to be involved in important interactions of immunological specificity of antigens and to participate in a variety of cellular functions.

Eating the right amount of carbohydrates is very important because carbohydrates are the more efficient fuel source for the body.
There are a large number of enzymes that are capable of modifying carbohydrates or carbohydrate derivatives, and that may be used in various analytical methods. The hydrolytic enzymes, which break glycosidic linkages, are useful in the study of disaccharide or polysaccharide structure and in methods for quantitation (Table 9.2). Such enzymes will hydrolyse the glycosidic linkages between the monosaccharide residues and release the individual components for further analysis. The enzyme is chosen bearing in mind the nature of the glycosidic linkage involved, which may not be unique to one particular disaccharide or polysaccharide. Thus a-glucosidase will hydrolyse both the a(l-»4) linkage of maltose and the a( 1-»2) linkage of sucrose, resulting in the release of glucose in both cases.. ...

When you look at your garden, consider that your herbs, trees, flowers and other plants all share common properties. They always try to maintain equilibrium-the point of perfect balance. Water and nutrients are absorbed into the root system and pulled up through the stems into the leaves. The plants then use Photosynthesis with the raw ingredients of water and energy from the sun to convert carbon dioxide into carbohydrates that plants use for growth and other plant functions.. Carbohydrates are stored in the branches and stems of herbs and other plants. These stored carbohydrates are used as reserve energy for the plant. When a crisis occurs, such as a broken stem or pathogenic attack, a plant can use these stored carbohydrates. Stored carbohydrates are also used in the spring to create new stems and foliage.. Soil organisms, from earthworms to fungi, provide needed nutrients to plant roots. A healthy root system allows herbs and other plants to create chemicals that repel pathogens and ...

1) THEY ARE AN EXCELLENT ENERGY SOURCE:- The primary function of carbohydrates is to provide your body with energy. When you ingest any form of carbohydrate (whether it be pure sugar, whole grain bread or a piece of fruit) it is broken down into glucose in the digestive tract. This glucose is then released into the bloodstream where your cells can use it for energy.. Your body can convert fats and proteins into energy through a process called gluconeogenesis. However, this process is very inefficient and prevents fats and proteins from performing their primary functions which are to build, protect and repair your bodys cells. Therefore, one big benefit of carbohydrates is that they provide your body with an easily accessible energy source.. 2) THEY ARE A RICH SOURCE OF FIBRE:- If you choose your carbohydrates wisely then you should be getting the majority from fruits and vegetables. Both of these plant based foods are an excellent source of insoluble and soluble fibre which have a number of ...

1. The sugars and amino sugars of hydrolysates of gastric secretion were determined by gas-liquid chromatography. 2. All the gastric aspirations examined showed on hydrolysis the presence of fucose, galactose, mannose, glucose, galactosamine, glucosamine, N-acetylneuraminic acid and sulphate. 3. Galactose and glucosamine were always found in equimolar amounts, but the galactose/galactosamine ratio in different aspirations was 2:1, 3:1, 4:1 or 5:1. Repeated gastric aspirations of each subject examined showed constant ratios of these carbohydrate components. 4. Fucose and sialic acid appear to be related to glucosamine and galactosamine respectively. 5. The carbohydrate components of extracts from the mucous glands of the body mucosa and antrum did not differ from those of gastric secretion.. ...
Carbohydrate consumed in food yields 3.87 calories of energy per gram for simple sugars,[16] and 3.57 to 4.12 calories per gram for complex carbohydrate in most other foods.[17] High levels of carbohydrate are often associated with highly processed foods or refined foods made from plants, including sweets, cookies and candy, table sugar, honey, soft drinks, breads and crackers, jams and fruit products, pastas and breakfast cereals. Lower amounts of carbohydrate are usually associated with unrefined foods, including beans, tubers, rice, and unrefined fruit.[18] Foods from animal carcass have the lowest carbohydrate, but milk does contain lactose. Carbohydrates are a common source of energy in living organisms; however, no carbohydrate is an essential nutrient in humans.[19] Humans are able to obtain most of their energy requirement from protein and fats, though the potential for some negative health effects of extreme carbohydrate restriction remains, as the issue has not been studied extensively ...
Introduction. The Role of Carbohydrates in Living Organisms Carbohydrates are composed of the elements carbon, hydrogen, and oxygen. The general formula is Cx(H2O)y. There are many different types of carbohydrates present in living organisms, each playing an important role in maintaining life of organisms. Monosaccharides are a group of carbohydrates, which include simple sugars such as glucose, fructose and galactose. Monosaccharides are classified according to the number of carbon atoms they possess. Trioses such as glyceraldehyde, and dihydroxyacetone contain three carbon atoms. The phosphorylated form of glyceraldehyde is the first formed sugar in photosynthesis, and may (like dihydroxyacetone) be used as respiratory substrate, or is converted to starch for storage. more. Middle. Galactose, mannose and fructose are three principal respiratory substrates in organisms. Additionally, Galactose is central in the synthesis of lactose. Fructose is also involved in the synthesis of insulin, ...
The American diabetes association 2000 calorie diet recommends carbohydrate counting as it is important to focus on balancing food intake, keeping sugar levels in check and physical activity. If diabetics opt for healthy foods each day theses have long term benefits in controlling their diabetes. Diabetics get their main source of energy through carbohydrates which are in starch, fruits, vegetables, sugars and dairy products. Carbohydrates are not present in meats and fats and it directly affects the blood glucose. Consuming carbohydrates in limited amounts at each meal time controls blood sugar levels. There are various means to knowing how much carbohydrate is present in each meal through carbohydrate counting. The amount of carbohydrate needed by an individual is determined by a dietician depending on their body weight, insulin levels, eating patterns and activity. 45 to 65 percent of a days calorie requirement should come from the carbohydrates consumed. Carbohydrate counting is considered ...
January 2016. Carbohydrate is the major source of energy for both cellular metabolism and ones diet. Carbohydrates can be either simple or complex. Simple carbohydrates- for which food science gives the more colloquial name sugar-are small in size, making them also sweet to the taste. The two classes of simple carbohydrates are called monosaccharides and disaccharides. As indicated by their prefixes, a monosaccharide comprises 1 sugar unit, while a disaccharide comprises 2.. In contrast, complex carbohydrates contain more than two sugar units. For this reason, they are called polysaccharides and are primarily chains of glucose. Unlike monosaccharides, they are larger in structure and not sweet to the taste. Plants store energy in the form of complex carbohydrates or what we commonly call starch. Starch is only found in plant products and some of its more familiar sources include all grains, potato, legumes (beans), and many vegetables.. Two major dietary sources of carbohydrate are ...
In the typical diet world there is a high amount of controversy over carbohydrate consumption. People everywhere have jumped onto the low carb bandwagon believing that this nutrient is most likely to lead to fat gain occurring.. Additionally, they firmly believe that carbohydrates are the primary reasons for so many diseases today and for optimal health, they needed to be eliminated.. Although there is truth in those statements, most people continue to miss the key factor; its the type of carbohydrates you are consuming more than anything else that matters.. Eat the wrong types of carbs consistently and youll be rewarded with weight and health problems whereas consuming the right types of carbohydrates eliminates those worries.. Its your job to time your carbohydrates properly and choose ideal sources.. Lets examine the different types of carbohydrates that youll come across daily:. Complex Carbohydrates:. These carbohydrates are high energy and complex in structure (meaning they take ...
Complex carbohydrates form one of the main dietary components. Carbohydrates are one of the three essential macronutrients required for the full functioning of the human body. They include sugars, starches, and fibers. Simple carbohydrates are sugars while complex carbohydrates include starch and fiber. They provide energy for the body, especially the brain and the nervous system. The energy is also used for functions like heartbeat, digestion, breathing and body movement. An enzyme, amylase, breaks down the carbs into glucose that is used for energy. Starch in food must be broken down through digestion before the body can use it as a dietary source. Complex carbohydrates consist of sugar molecules stuck together in long chains and branches. The body turns both simple and complex carbohydrates into glucose (blood sugar). Glucose is used in the cells of the body and in the brain. Any unused glucose is stored in the liver and muscles as glycogen for use later. Due to their complexity, complex ...
The best carbohydrates are complex, which is rich in fiber and nutrients, and low sugar content. For example oatmeal, grains, brown rice, brown rice, and black rice.. The process of digesting complex carbohydrates takes longer, so weight loss will occur. The energy it produces is also greater and last longer.. Meanwhile, bad carbohydrates have high sugar content and low in fiber. Called bad because it quickly makes hunger and excessive appetite. The effect is increasing the number of calories and fat deposits.. Bad carbohydrates are simple, for example, white rice, noodles, various pasta, pastries, and white bread. Boiled potatoes are often consumed as a substitute for white rice in the diet, but actually also included in simple carbohydrates. Potatoes should be consumed at certain times.. ...
Polysaccharides, also called as glycanes, are high molecular weight which on hydrolysis yield monosaccharides. Some sources of complex carbohydrates are pasta, bread, rice, cereals, crackers, corn, beans, potatoes, pumpkin, and peas. Digestion of complex carbohydrates could take more time because digestive enzyme have to work harder to break down the chain into individual sugars. Complex carbohydrates contain hundreds of sugar units. Studies show that glucose levels both rise and fall more slowly after the consumption of bread compared to sugars or fruit, suggesting slower digestion.[1] Both monosaccharides and disaccharides are used only for energy. Another difference is that while monosaccharides and disaccharides can be used for energy immediately, polysaccharides release their energy slowly. Research shows that the carbohydrate oxidation rate rises more slowly after the consumption of bread rather than sucrose following an overnight fast. The carbohydrate oxidation rate is also lower over a ...
Carbohydrate counting or carb counting is a meal planning tool used in diabetes management to help optimize blood sugar control. It can be used with or without the use of insulin therapy. Carbohydrate counting involves determining whether a food item has carbohydrate followed by the subsequent determination of how much carbohydrate the food item has in it. Carbohydrate is one of three major macronutrients found in food. The other major macronutrients are protein and fat. Carbohydrate in its simplest form is known as glucose and can contribute to a rise in blood sugar. In people with diabetes, the bodys ability to keep blood sugar at a normal level is impaired. Dietary management of carbohydrate consumed is one tool used to help optimize blood sugar levels. Carbohydrate is found in a number of foods including fruits, starchy vegetables (such as peas, potatoes, and corn), grains, milk and yogurt, legumes, and desserts. In general, foods such as meat, eggs, cheese, fats, and non-starchy ...
Foods containing carbohydrate are grouped into the following categories. The carbohydrate content is listed in grams (g). If you eat a larger portion, count it as more than one serving.. One serving of carbohydrate has 15 grams of carbohydrate. Of course, not all foods contain exactly 15 grams of carbohydrate. Typically if a food has 8 to 22 grams of carbohydrate, that is equal to 1 carbohydrate serving. ...
We know that carbohydrates are both healthy and unhealthy, and that a slight change in the structure of a carbohydrate can make it act like an enemy to the body.. It is important to know which carbohydrates are good and which are bad carbs.. Bad carbs, like refined flours and processed sugars, are bad because once they enter the bloodstream they immediately raise your bodys sugar levels. Once your body has an increase of sugar levels, your body chemistry immediately shifts and you begin to store fat instead of burning it off. Your body takes energy from the ample blood sugar and converts everything else to fat cells which will be stored under your skin until which time they are needed for energy reserves.. The bad carbohydrates Refined carbohydrates include tasty foods like candy bars, sodas and sugary snacks, but also French fries, potato chips, white breads, pastas (that arent whole grain), white rice, cornmeal, and many other refined starches.. Bad carbohydrates do not need to be outright ...
The goal of this thesis is to examine the distribution and diagenesis of carbohydrates in aquatic environments. The following questions are studied: what is the carbohydrate composition of sediment in different environments (e.g., deep-sea oxic; shallow-sea oxic; deep-sea anoxic; fresh-water anoxic; brackish-water anoxic, etc.)? How does the environment at the sediment-water interface affect the composition of the carbohydrate input? How do sedimentary carbohydrates compare to plankton carbohydrates? How do metal-carbohydrate interactions and biological degradation affect the diagenesis of carbohydrates in recent sediments? Can fossil carbohydrates be used as a means to elucidate paleo-environments? In order to investigate these questions in a quantitative manner, a liquid chromatographic sugar analyzer sensitive to 10-10 moles was constructed. Various extraction techniques, involving acid hydrolysis and EDTA treatment, were thoroughly examined to determine lability of sugars, sources of ...

Particular attention was given to cope with the accepted nomenclature and pictorial representation used in glycoscience. This achievement provides a continuum between the most popular ways to depict the primary structures of complex carbohydrates to visualizing their 3D structures while giving the users many options to select the most ...
All our energy comes from carbohydrates because the muscles get their glycogen which they use for energy from the breakdown of carbohydrates. But eating carbs in order to help you gain muscle needs to be carefully considered as eating simple sugars is definitely not the answer.. We need to understand the difference between a simple carbohydrate and a complex carbohydrate. All simple carbohydrates are sugars like glucose, fructose and sucrose which are just one or two molecules attached to a sugar molecule. Complex carbohydrates are made of three or more sugar molecules and will include all starches as well as any fiber.. Complex carbohydrates take longer to break down into glucose so this means that the use of glucose for normal bodily functions and any activity done means that it will be able to be sustained for a longer period of time. The effect when trying to build muscle will be radically changed when glucose is gotten from complex carbs as opposed to simple carbs.. For example a person ...
The way carbohydrates are demonized today, its no wonder that so many people actually fear eating them. I used to be one of them. As a recovering carb-o-phobe, Im now on the flip side and advocate eating complex carbohydrates for optimal nutrition.. Carbohydrates are nutrients that act as a good source of energy for our body. It is made up of sugar, starch and cellulose and it contains hydrogen and oxygen in the ratio 2:1which is the same as that of water. Although carbohydrates can be digested a lot easier than fats or proteins, they arent considered indispensable for the body.. While some carbohydrates make us healthy, others can be harmful to our health, if taken in excess quantities. For example, certain carbohydrates increase the risk of diabetes and heart ailments. So why are certain carbohydrates are beneficial and others adversely affect our health?…We need to go deeper and learn about the different forms of carbohydrates.. There are many forms of carbohydrates, but the three ...

Nutrients for Health Carbohydrates: Carbohydrates are our energy food or what we call macronutrients. There are three other macronutrients in our diet in addition to carbohydrates Paul Molitor Jersey , which are proteins, fat and alcohol. It is important to understand that a carbohydrate is not a food, but rather a very important component of food. Foods such as cereals, breads, pasta, rice, fruits and some vegetables (e.g. potato) are called carbohydrates but strictly speaking these are carbohydrate-rich foods. Carbohydrates are the single most important source of energy in our diet. For a healthy heart, carbohydrates should make up about 55% of daily energy needs from food intake. Most carbohydrate-rich foods are also rich sources of vitamins (particularly B-vitamins and folate), minerals (including Iron and Zinc), as well as fibre and phytochemicals (other natural components of food found to be beneficial for health.) Carbohydrates are a combination of the following: 1.Starch - found in ...

Membrane carbohydrates may work as a physical barrier that protects the cell, but they also may carry out other important functions for the cell. For example, they are molecules for recognition and binding in cell-cell signalling. Blood groups are determined by cell surface carbohydrates, which also have the ability to trigger immunological responses. After an infection, endothelial cells close to injured tissue expose a type of proteins, known as selectins, in their plasma membranes which recognize and bind to carbohydrates of the plasma membrane of lymphocytes in the bloodstream. In this way, lymphocytes get attached to the blood vessel walls, can cross the endothelium and go to the infection focus. Carbohydrates as recognition molecules are also important during embryonic development, and also during pathogen infection. Virus, such as influenza virus, pathogenic E. coli bacteria, and some protozoa need to be attached to the cell surface before entering the cell, because otherwise they will be ...

The amount and type of carbohydrates in your diet can be the most important factor to weight loss and fat reduction. Carbohydrates are NOT created equally, so you have to be aware of what type of carb you are adding to your diet! Carbs need to be eaten with care- there is a distinct difference between good and bad carbs.. When carbohydrates are consumed, they are broken down into sugar, the sugar is then absorbed into the blood stream as glucose or blood sugar! This is the sugar that feeds our brain and gives us energy- however too much sugar or the wrong kind can make us gain weight! The wrong sugars will not be effectively processed by our body and will be stored as fat. Even eating too much good sugar can slow down the process and cause slow to no weight loss! BE AWARE of your SUGAR INTAKE!!! (you want to stay between 5-15% of your daily caloric intake). ...
The proximate analysis system attempted to separate dietary carbohydrates into fiber and non-fiber portions. Under this system, any matter unaccounted for after subtraction of ash, crude protein, ether extract, and crude fiber from total dry matter was assumed to be non-fiber carbohydrates. Due to loss of variable amounts of fiber (cellulose and hemicellulose) and lignin during analysis, the proximate analysis system frequently overestimated non-fiber carbohydrates and underestimated fiber to a degree that could not be determined. The neutral detergent system allowed accurate determination of fiber and lignin, improving the accuracy of non-fiber carbohydrate (NFC) estimation, but with no differentiation between NFC fractions. Non-fiber carbohydrates can be separated into sugars, starch, organic acids, and pectic substances known as neutral detergent-soluble fiber (NDSF), distinct fractions which merit individual consideration in diet formulation.. ...

Ever since humans switched from nomads and their hunter-gatherings roles, to that of an agrarian-based society, western cultures have looked to the carbohydrate as a primary food staple. For example, an average person in America cannot envision a day without pastries, potatoes, corn, bread, cereal or rice.. The media has made us well aware that the excessive intake of carbohydrates has a detrimental effect on our waistlines, but how much do we know about the effect they have on our health? What adds to the sad situation is these carbohydrates are consumed in a highly processed form. What do we get from eating processed starches? Well 65% of Americans are overweight and 30% of them are clinically obese.. These refined carbohydrates in our diets are causing numerous diseases like diabetes in epidemic proportions. The symptoms are very simple, if you experience fatigue, sleepiness, fogged thought process, bloating of the abdominal area, high triglyceride levels, high blood pressure levels or low ...
How much carbohydrate you need depends on the intensity and volume of training, gender, and type of sport. Research indicates that elite (college and professional) athletes need 6-12 grams of carbohydrate per kilogram of body weight (weight in kilograms = weight in pounds divided by 2.2). Women and less active athletes will be on the lower end of that range, while men or endurance athletes will be on the higher end. However, most recreational athletes will need fewer carbohydrates, as they are not training over 2 hours per day as those athletes do. For most people I recommend 3-6 grams/kg of body weight, depending on your training. For example, a runner who does CrossFit twice a week and is trying to maintain weight will want to eat more carbohydrates than someone who does CrossFit four times a week and is trying to lose weight.. The thing about carbohydrates is there is not enough evidence to recommend exact levels to everyone. How much you need depends on your training, weight, and goals, but ...

Ive mentioned before that I listen regularly to the Paleo Solution podcast with Robb Wolf. On this past podcast he had board certified neurologist Dr. David Perlmutter. Dr. Perlmutter sees, among other patients, many Alzheimers patients and has really done his homework on causes of the disease. Hes written a book called Grain Brain where he discusses in great detail the negative effect of carbohydrates on the brain (among other things). The more I learn about these things, and do my own research, the more Ive come to believe that our bodies are simply designed to run lean on carbohydrates. Now, before folks go getting their britches wadded up like they so often do when I talk about this stuff, Im not vilifying carbohydrates. Its just that our society now has access to SO MUCH carbohydrate that average folks can too easily over-consume. ...
Carbohydrates are a source of energy in our diet. When we eat foods that contain carbohydrates, the energy in them is changed in our cells to a form that our bodies can use. Carbohydrates also form building materials like the chitin that covers the surface of insects and cellulose that makes up plant cell walls. Carbohydrates are the group that includes simple sugars and more complex molecules made up of lots of sugars bonded together. A carbohydrate made of two sugars is called a disaccharide. An example of this is sucrose, which is table sugar like you may put on your cereal or use to make cookies. Continued.... ...

2016). As such, the research performed over the past decade using simple systems and metabolomics has generated a general conceptual framework that appears generally applicable to many systems. The findings suggest that glucose is primarily converted to lactate in proliferative metabolism. The fate of glucose in proliferating cells trifurcates toward the pentose phosphate pathway, glucosamine biosynthesis, and glycolytic degradation to lactate. The pentose phosphate pathway generates an essential component of nucleic acids: ribose, which would then be reduced to deoxyribose by deoxyribonucleotic reductase. Glucosamine, which is at the crossroads of glucose and glutamine metabolism, is critical for carbohydrate synthesis and posttranslational modification via O-linked glycosylation, for example. The conversion of glucose to lactate with the regeneration of NAD+ from NADH ensures the upstream glycolytic flux through GAPDH, which depends on NAD+, continues to funnel pyruvate downstream for its ...

  • Most vegetables are low- or moderate-carbohydrate foods (in some low-carbohydrate diets, fiber is excluded because it is not a nutritive carbohydrate). (
  • One of the most important findings here is that the type of carbohydrate-containing foods you consume can impact your cancer risk. (
  • It appears that healthy carbohydrate sources, such as legumes, tend to protect us from cancer, but non-healthy ones, such as fast foods and sugary beverages, seem to increase the risk of these cancers. (
  • Grain products are staple foods and sources of simple and complex carbohydrates that provide energy for the body. (
  • Most carbohydrates come from foods of plant origin. (
  • All the foods above are carbohydrates. (
  • But the second option in both questions includes good carbohydrate foods (whole grains and vegetables). (

(
  • Complex carbohydrates are high-fiber foods, which improve your digestion. (

  • Therefore in SI units carbohydrates provide the body with 16.7 mega joule of energy for each kilogram. (
  • People who depend on carbohydrates as their major fuel source - let's call them "sugar burners" - typically fall victim to the whims of the storage hormone insulin. (
  • Calories from simple, refined carbohydrates (especially sugar) stimulate the release of the building and storage hormone insulin. (
  • By performing a balancing act with carbohydrates, exercise, and insulin, you can keep your blood sugar in line and still enjoy good eats. (
  • When people eat simple carbohydrates , a gland called the pancreas secretes insulin--a hormone that helps muscle cells absorb sugar. (
  • If you eat more carbohydrates than your insulin supply can handle, your blood sugar level goes up. (
  • Carbohydrate structures play critical roles in immune system function and carbohydrates also have the virtue of a strong safety and tolerability record. (
  • Carbohydrate-active enzymes are the biological catalysts that synthesize and break down the multitude of complex carbohydrate structures found in nature. (
  • Carbohydrates can have various structures. (
  • After you eat food that has carbohydrates in it, your blood sugar goes up. (
  • If you're not sure how many carbohydrates a food contains, check the label or ask your doctor or nutritionist. (
  • Yogurt is highly variable in carbohydrate content, so check the food label to be sure. (
  • GI measures the quality of a dietary carbohydrate based on an item's relative impact on blood sugar levels, compared with a reference food. (
  • GL measures the quantity and quality of carbohydrates in a specific food item. (
  • Through clinical and epidemiological studies, Functional Food Carbohydrates addresses the specific classes of carbohydrates that seem to exert health-enhancing effects. (
  • In practical terms, this works out in the following way: a young athlete consuming 2,500 calories a day needs on average about 1,250 carbohydrate calories daily, equivalent to about 312 g (11 oz) of carbohydrate food, or 6 to 11 servings. (
  • What Food Groups Are Carbohydrates Found in? (
  • If they are used as a sweetener in food that contains few calories and no other carbohydrate (such as sugar-free soft drinks or sugar-free gelatin), that food is considered to be a 'free food. (
  • How do you use the food label to count carbohydrates? (
  • You may have been aware of the term "Carbohydrates" and you know that they are abundant in different food sources. (
  • Your body needs all three forms of carbohydrates to function properly. (
  • Kiliani-Fischer Synthesis- a series of reaction that extends carbon chain in a carbohydrate by one carbon and one chiral centre. (
  • Carbohydrates are macromolecules composed of carbon (C), hydrogen (H) and oxygen (O) and have the general formula of Cx(H2O)y. (
  • A carbohydrate is an organic compound with general formula C''m''(H2O)''n'', that is, consisting only of carbon, hydrogen and oxygen, the last two in the 2:1 atom ratio. (
  • Carbohydrates can be viewed as hydrates of carbon, hence their name. (
  • A carbohydrate is an organic compound consisting of a chain or ring of carbon atoms to which hydrogen and oxygen atoms are attached in the ratio of approximately 2:1. (
  • Most carbohydrates have a ratio of 1:2:1 of carbon, hydrogen, and oxygen, respectively. (
  • The term Carbohydrates can actually be derived from Carbon, Hydrogen and Oxygen. (
  • This term persists even though a carbohydrate definitely is not a hydrated carbon atom . (
  • Each carbon atom that supports a hydroxyl group (except for the first and last) is optically active, allowing a number of different carbohydrates with the same basic structure. (
  • Find the latest news, plus links to overviews, clinical trials and research related to dietary carbohydrates. (
  • Avocado pear and the olive has a high fat content but low carbohydrate content. (
  • It became clear that young trees with more stored carbohydrates were able to maintain the vital water content in the stem for longer than those with fewer stored carbohydrates. (
  • The new study, led by Professor David Rowley from the University of Rhode Island, concluded that certain carbohydrates in cranberry may also contribute to the fruit's overall anti-infective properties, in addition to the specific proanthocyanidin content of cranberry. (
  • They are also called simple carbohydrates because they are in the most basic form. (
  • Carbohydrates are classified as simple or complex depending on their chemical structure and how quickly the sugar is digested and absorbed. (
  • There are two types of carbohydrate: complex and simple. (
  • Simple carbohydrates (sugar) cause tooth decay. (
  • Finish the meal with fruit, and this should ensure you get a balance of complex and simple carbohydrates. (
  • What are simple carbohydrates? (
  • Since they are larger and more complex molecule, before being absorbed they have to break down in simple carbohydrates so as to be assimilated. (
  • Scientists and dietitians used to group carbohydrates into two types: complex carbohydrates and simple carbohydrates. (
  • In contrast, sugar and other simple carbohydrates can alter your mood, lead to cravings and compulsive eating, cause wide swings in your blood-sugar levels, and cause weight gain in most people. (
  • If you are to describe the structure of simple carbohydrates, you can be able to see that there are ketones or aldehyde components. (
  • In fact, not eating enough carbohydrates can hurt you. (
  • Aside from that, you should be able to understand that there are actually a lot of benefits of having enough carbohydrates in your body. (
  • From each of these sources and others, carbohydrates provide you with 4 kcals/gram. (
  • Each gram of carbohydrate povides 4 calories. (
  • Carbohydrates are one of the fundamental classes of macromolecules found in biology . (
  • This previously unknown biological function extends the group of carbohydrate-active enzymes to include the class of cytochrome P450 monooxygenases. (
  • Include them in your daily carbohydrate count. (
  • It will include original studies and comprehensive reviews on the primary structure, molecular characteristics including conformation, size and shape, and bioactivities demonstrated by studies using in vitro , cell culture, animal and human clinical trials for understanding the action mechanisms and efficacy of bioactive carbohydrates from plants, fungi, animals and produced by biotechnology. (
  • Carbohydrate derivatives are involved in reproduction, the immune system, the development of disease, and blood clotting. (
