TY - JOUR. T1 - Kinetic modeling of a bi-enzymatic system for efficient conversion of lactose to lactobionic acid. AU - Van, Wouter. AU - Bhagwat, Aditya. AU - Ludwig, Roland. AU - Dewulf, Jo. AU - Haltrich, Dietmar. AU - Van Langenhove, Herman. PY - 2009/4/1. Y1 - 2009/4/1. N2 - A model has been developed to describe the interaction between two enzymes and an intermediary redox mediator. In this bi-enzymatic process, the enzyme cellobiose dehydrogenase oxidizes lactose at the C-1 position of the reducing sugar moiety to lactobionolactone, which spontaneously hydrolyzes to lactobionic acid. 2,20 Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt is used as electron acceptor and is continuously regenerated by laccase. Oxygen is the terminal electron acceptor and is fully reduced to water by laccase, a coppercontaining oxidase. Oxygen is added to the system by means of bubble-free oxygenation. Using the model, the productivity of the process is investigated by simultaneous solution ...
A disaccharide (also called a double sugar or bivose[1]) is the sugar formed when two monosaccharides (simple sugars) are joined by glycosidic linkage. Like monosaccharides, disaccharides are soluble in water. Three common examples are sucrose, lactose,[2] and maltose. Disaccharides are one of the four chemical groupings of carbohydrates (monosaccharides, disaccharides, oligosaccharides, and polysaccharides). The most common types of disaccharides-sucrose, lactose, and maltose-have 12 carbon atoms, with the general formula C12H22O11. The differences in these disaccharides are due to atomic arrangements within the molecule.[3] The joining of simple sugars into a double sugar happens by a condensation reaction, which involves the elimination of a water molecule from the functional groups only. Breaking apart a double sugar into its two simple sugars is accomplished by hydrolysis with the help of a type of enzyme called a disaccharidase. As building the larger sugar ejects a water molecule, ...
Aims: Iron deficiency is common in patients with chronic kidney disease (CKD). Appropriate iron substitution is critical and intravenous iron is an established therapy for these patients. The objective of this study was to assess treatment routine, effectiveness, and safety of iron isomaltoside (Monofer (R), Pharmacosmos A/S, Holbaek, Denmark) in CKD patients in clinical practice.

Disaccharides (sugars): Disaccharides are commonly referred to as sugars. Disaccharides are composed of two monosaccharides joined together. When the two molecules join together a molecule of water is released. The disaccharide sugars include Sucrose, Lactose,and Maltose.. Glucose + Fructose = Sucrose. Glucose + Galactose = Lactose. Glucose + Glucose = Maltose. These different disaccharides contribute to various levels of sweetness in foods. Sugars are found naturally in fruit and vegetables, and are also found in many processed foods. Processed foods usually contain much more sugar than natural foods. Sugars act as sweeteners in food but they are also very high in energy. This is a concern because sugars make up a large part of the diet and if the energy isnt expended, the body stores the enrgy as fat. Excessive sugar in the diet can lead to nutritional disorders such as obesity and dental caries.. Polysaccharides: are very large moleculeswhich are formed from many monosaccharides joined ...
The molecular structure of human skin fibroblast heparan sulphate was examined by specific chemical or enzymic depolymerization and high-resolution separation of the resulting oligosaccharides and disaccharides. Important features of the molecular organization, disaccharide composition and O-sulphate disposition of this heparan sulphate were identified. Analysis of the products of HNO2 hydrolysis revealed a polymer in which 53% of disaccharide units were N-acetylated and 47% N-sulphated, with an N-/O-sulphate ratio of 1.8:1. These two types of disaccharide unit were mainly located in separate domains. Heparitinase and heparinase scission indicated that the iduronate residues (37% of total hexuronate) were largely present in contiguous disaccharide sequences of variable size that also contained the majority of the N-sulphate groups. Most of the iduronate residues (approx. 70%) were non-sulphated. About 8-10% of disaccharide units were cleaved by heparinase, but only a minority of these originated ...

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 ...

Glycosaminoglycans (GAGs) are found mainly in connective tissue as constituents of proteoglycans, covalently linked to the core protein. They participate in and regulate several cellular events and physiological processes. The sequence of [Delta]-disaccharides in GAGs is crucial for their proper function. The human xylosyltransferases XT-I and XT-II catalyse the initial and rate-limiting step in the biosynthesis of GAGs by the transfer of xylose to selected serine residues in the core protein of proteoglycans (PGs). For the analysis of GAGs, a HPLC method facilitating the separation of 16 [Delta]-disaccharide standards derivatized with the fluorophore 2-aminoacridone was developed. This novel method allows the quantitative analysis of the [Delta]-disaccharide composition of hyaluronic acid (HA), chondroitin sulfate (CS), dermatan sulfate (DS), heparan sulfate (HS) and heparin (H). The method represents the first HPLC application ever to accomplish baseline separation of either seven ...

N-acetyl-L-cysteine bearing free carboxylic acid and sulfhydryl groups was glycosylated with 1,2,3,4,6-Penta-O-acetyl-ß-D-glucopyranoside in the presence of SnCl4 as a promoter to give the S-glycosylated cysteine in 64 % yield. However, when excess donor was used, a previously unreported cysteine-bridged disaccharide was isolated in 54 % yield. The acetamido group on cysteine, which lowers the pKa of the carboxylic acid group of the amino acid, plays no role in the formation of the bridged disaccharide since 3-mercaptopropionic acid reacts in a similar manner to give the 3-mercaptopropionic acid-bridged disaccharide in 52 % yield..

The disaccharide important for the nutrition is㴗 other sugars too a rigid, but a flexible structure. Sucrose, ordinary table sugar, is probably the single most abundant pure organic chemical in the world and the one most widely known to nonchemists. Whether from sugar cane (20% by weight) or sugar beets (15% by weight), and whether raw or refined, common sugar is still sucrose. Sucrose is a disaccharide that yields 1 equiv of glucose and 1 equiv of fructose on acidic hydrolysis. This 1:1 mixture of glucose and fructose is often referred to as invert sugar, since the sign of optical rotation changes (inverts) during the hydrolysis from sucrose ([alpha]D = +66.5°) to a glucose fructose mixture ([alpha]D = -22.0°). Certain insects, particularly honeybees, have enzymes called invertases that catalyze the hydrolysis of sucrose to a glucose-fructose mixture. Honey, in fact, is primarily a mixture of these three sugars. Unlike most other disaccharides, sucrose is not a reducing sugar and does not ...

There are polysaccharides, disaccarides, and monosaccharides. From my research polysaccharides and disaccarides (like bread and such) ferment longer in the gut, where monosaccharides can absorb more quickly. Polysaccharides and disaccharides are longer chains and take longer to break down whereas monosaccharides absorb more quickly. For someone with Candida, monosaccharides are not ideal because it means the Candida can absorb more quickly, and depending on where it has grown to e.g. moved its way into your small intestine, it can be bad eating sugar. From my understanding, Candida is typically located in the colon, but it works its way up into the small intestine and else where, sometimes even in the mouth when it gets pathogenic. If it is not within your small intestine, monosaccharides in small amounts I presume would be absorbed before they hit the colon. I would try to avoid sugar in general and when things become manageable and never eat processed sugar if you can keep from it. Since we ...
researchers suggest that sweetness, for which there are receptors on the tongue, signaled a safe energy source and thus became an important energy source for humans.. We need carbohydrates to add sugars to other molecules - glycoproteins, glycolipids - receptors for hormones. There are no essential sugars. (However, carbohydrate intake is considered to be essential because sugar provides all the fuel for the brain). Most forms of carbohydrates are composed of carbon, hydrogen and oxygen in the ratio of 1:2:1. The general formula is CH2O:. The simple forms of carbohydrates (monosaccharides and disaccharides) are called sugars. More complex forms of carbohydrate (polysaccharide) are called starch and dietary fiber.. Simple carbohydrates = SUGARS. Monosaccharides (1 carbon ring). • Serve as the basic unit of all sugar structures. • Rapidly absorbed into bloodstream from small intestine. • glucose (also known as dextrose) - the major monosaccharide found in the human body. Glucose is stored in ...
Sugar, by any name, is - sugar. The simple carbohydrates are monosaccharides - glucose and fructose. Disaccharides are chemical pairs of the monosaccharides, such as sucrose. Sucrose, or common table sugar consists of half glucose and half fructose. Glucose is the basic energy form of carbohydrate that fuels every cell of the body, and is the fuel of choice in the brain. All carbohydrates break down into glucose (blood sugar); some take longer, depending on how complex. One gram of sugar or any carbohydrate, provides 4 calories. 50% of your daily calorie intake should be in the form of carbohydrates. Is one form of dietary sugar any better or "healthier" than an other? No. Here is the chemical breakdown on sugar ...
Carbohydrates Lecture II Highlights. 1.Linking together of more than one sugar residues creates higher order saccharides. These include disaccharides (two sugars), trisaccharides (three sugars), oligosaccharides (several sugars), and polysaccharides (many sugars).. 2. Most of the linkages in higher order saccharides involve glycosidic bonds.. 3. Disaccharides include sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (two glucoses). Linkages of these are shown in the figures in the notes. 4. Sucrose is a non-reducing sugar (has no free anomeric hydroxyl), whereas lactose is a reducing sugar (has a single free anomeric hydroxyl). The sucrose figure in your book shows a confusing structure. HERE is a better one. You are responsible for the structure of sucrose and the linkages for the disaccharides I described in class.. 5. Oligosaccharides are components of glycoproteins.. 6. The most common polysaccharides include glycogen (energy storage in animals), cellulose (structural ...

Furcellaran is anionic partly sulphated polysaccharide which is classified together with carrageenan (E407).. The structure of furcellaran is similar to that of kappa carrageenan and has been described as a hybrid of kappa/beta carrageenans complex. The essential difference is that kappa carrageenan has one sulphate ester residue per two sugars, while furcellaran has one sulphate ester residue per three or four sugar residues.. Furcellaran is polysaccharide consisting of repeated disaccharide units of beta (R1 = R2 = H) and kappa carrageenan (R1 = SO3-, R2 = H). The structures of repeating disaccharide units of furcellaran and carrageenan are shown in figure 1.. ...

Advances in the elaboration of vaccines and enzyme inhibitors rely on acquiring more knowledge about protein-carbohydrate binding events. Furthermore, the relationships between biological function and the three-dimensional properties of large glycans can be studied by focusing on the structural components they contained, namely, by scaling down the system under analysis. Chemical methods are useful assets as they allow the isolation and determination of epitopes; these small and recognizable fragments that lead to very specific interactions. In this thesis, biologically relevant saccharides were obtained using recently developed concepts in carbohydrate synthesis and NMR spectroscopy was used to unravel their conformational preferences.. In paper I, the convergent synthesis of the tetrasaccharide found in the natural product solaradixine is described.

Ang carbohydrate ay isang organikong compound na may empirikal na pormulang Cm(H2O)n (kung saan ang m ay maaaring iba mula sa n). Ito ay nangangahulugang ito ay binubuo ng carbon, hydrogen at oxygen na may hydrogen:oxygen atomong rasyo na 2:1 gaya ng sa tubig. Gayunpaman, may mga ilang eksepsiyon dito. Ang isang karaniwang halimbawa ay deoxyribose na isang sangkap ng DNA na may empirikal na pormulang C5H10O4. Ang mga carbohydrate ay maaaring makita bilang mga hydrate ng carbon kaya ito ang pangalan nito. Gayunpaman, sa istraktura nito, mas wastong makita ang mga ito bilang mga polyhydroxy aldehyde at ketone. Ang terminong ito ay pinakaramiwan sa biokemistri kung saan ito ay sinonimo ng saccharide. Ang mga carbohydrate o saccharide ay nahahati sa apat na mga kemikal na pagpapangkat: monosaccharide, disaccharide, oligosaccharide, at polysaccharide.

N-acetylation is a major metabolic pathway for EDA in the rat. In the urine, AcEDA accounts for approximately half of the radioactivity. The data on the ion-exchange chromatography of aqueous fecal extract also revealed the presence of AcEDA as a major metabolite. In addition to acetylation, the enzymatic formation of aminoacetaldehyde from EDA as suggested by Hoshika (1967) is highly probable in the rat. If this reaction happens in vivo, it is conceivable that CO2 might be generated from ethanolamine, a probable metabolite of aminoacetaldehyde, through a series of reactions as discussed by Taylor and Richardson (1967 ...
