TY - JOUR. T1 - Total free amino acid levels in adult and senescent rat liver. AU - Eichholz, R. L.. AU - Buetow, D. E.. PY - 1978. Y1 - 1978. N2 - The total free amino acid content per gram of liver wet weight does not differ significantly between adult and senescent female rats, being 28.8 ± 3.3 μmol in adult (13-17 months) and 26.2 ± 2.2 μmol in senescent (23-29 months) animals. This is the first study in which these two age-groups of rats have been so compared. These results combined with a survey of the literature show that amino acid levels in rat liver do not change much, if at all, throughout the lifespan of the animal..

TY - JOUR. T1 - Effect of leucine-lsoleucine antagonism on plasma amino acid pattern of rats. AU - Rogers, Quinton. AU - Spolter, P. D.. AU - Harper, A. E.. PY - 1962/1/1. Y1 - 1962/1/1. N2 - The rate of stomach-emptying, the nitrogen content of the intestinal contents, and the blood plasma amino acid pattern of rats were determined at various time intervals up to 24 hr. after they had consumed a single low-protein meal containing enough leucine to cause a leucine-isoleucine and valine antagonism. Control groups were fed either the basal diet without additional leucine or the high-leucine diet with extra isoleucine and valine to alleviate the antagonism. No significant differences were found between the rates of stomach-emptying, or between the amounts of nitrogen in the intestinal contents, of the groups fed the high leucine diets with or without extra isoleucine and valine. The concentrations of isoleucine and valine in blood plasma from the group receiving excess leucine alone were lower ...
Proteinogenic amino acids, also known as standard, normal, or primary amino acids, are those 20 amino acids that are found in proteins and that are coded for in the standard genetic code. Proteinogenic literally means protein building. Proteinogenic amino acids are assembled into a polypeptide (the subunit of a protein) through a process known as translation (the second stage of protein biosynthesis, part of the overall process of gene expression). Non-proteinogenic amino acids are either not found in proteins (like carnitine, GABA, or L-DOPA), or not coded for in the standard genetic code (like hydroxyproline and selenomethionine). The latter often result from posttranslational modification of proteins. Some non-proteinogenic amino acids, such as ornithine and homoserine have clear reasons why organisms have not evolved to incorporate them into proteins; both of these amino acids will cyclize against the peptide backbone and fragment the protein with relatively short half-lives. Some ...

Unfortunately, this study leaves us with way more questions than answers. I personally, for example would venture the guess that the ingestion of a complete EAA product would result in an even more profound amelioration of the fasting induced reduction in fractional protein synthesis. That being said, the latter could also compromise another advantage of the non-essential amino acids, I have not even mentioned, yet: their almost non-existent effect on intra-muscular AMPK-expression (cf. figure 2, right). If you read all Intermittent Thoughts articles which dealt with the AMPK/mTOR Metabolic Seesaw and the respective follow-ups, you will be familiar with notion that the fasting-induced phosphorylation of intra-muscular AMPK is responsible for the majority of the health, as well as the closely related fat-burning effects of (intermittent) fasting. Now, if the ingestion of a ~20g bolus of alanine, glycine, proline, histidine, asparagine and serine could increase your skeletal muscle protein ...
It is not quite clear so far to what extent the requirement for total non-essential N can be influenced by the presence or absence of different non-essential amino acids. There are a number of studies indicating that some amino acids, commonly classified as non-essential, may have essential character (Breuer et al., 1964; Newburg et al., 1975; Ball et al., 1986; Roth et al, 1994a) whereas some others are inferior as sources of non-specific N (Sugahara and Ariyoshi, 1967b; Allen and Baker, 1974). Therefore, both the specific requirements for non-essential amino acids and the value of these amino acids in supplying the organism with non-specific nitrogen should be taken into account when studying the optimum E:T ratio and formulating amino acid diets.. Results of studies aimed at identification of non-essential amino acids needed for normal performance have been controversial. The requirement for proline has been demonstrated in rats (Breuer et al., 1964; Heger et al., 1987), chicks (Sugahara and ...

Before going ahead and understanding proteins - the biomolecules, it is important to first understand amino acids. Amino acids are the organic compounds mainly bonded to a hydrogen atom, a carboxyl group (COO-) and an amine group (NH2) along with a side chain (represented as R in the diagram) which is specific to every amino acid. There are about 500 amino acids known. The two broad groups into which these amino acids can be distributed are: proteinogenic amino acids and non-proteinogenic amino acids. The word proteinogenic means protein building. Interesting to note is that of these 500 amino acids, only 23 naturally occurring amino acids come under proteinogenic amino acids i.e.; these amino acids are precursors to proteins. Of these 23, 20 proteinogenic amino acids are encoded by codons (triplet) in genetic code and are called standard amino acids. The other three which are non-standard amino acids are pyrrolysine, selenocysteine and N-formylmethionine. The pyrrolysine is found in ...

1. After ingestion of up to 1-2 g of protein/kg body weight by adults, plasma concentrations of all amino acids, including glutamine and glutamic acid, rose to a maximum within 5 h.. 2. The increases in concentration depended on the amount of protein ingested.. 3. The changes were not due to diurnal variation in plasma amino acid levels, so, protein loading tests may be of value in the assessment of protein absorption. ...
Mass spectrometry-based serum metabolic profiling is a promising tool to analyse complex cancer associated metabolic alterations, which may broaden our pathophysiological understanding of the disease and may function as a source of new cancer-associated biomarkers. Highly standardized serum samples of patients suffering from colon cancer (n = 59) and controls (n = 58) were collected at the University Hospital Leipzig. We based our investigations on amino acid screening profiles using electrospray tandem-mass spectrometry. Metabolic profiles were evaluated using the Analyst 1.4.2 software. General, comparative and equivalence statistics were performed by R 2.12.2. 11 out of 26 serum amino acid concentrations were significantly different between colorectal cancer patients and healthy controls. We found a model including CEA, glycine, and tyrosine as best discriminating and superior to CEA alone with an AUROC of 0.878 (95% CI 0.815-0.941). Our serum metabolic profiling in colon cancer revealed ...
The α-ketoglutarate family of amino acid synthesis (synthesis of glutamate, glutamine, proline and arginine) begins with α-ketoglutarate, an intermediate in the Citric Acid Cycle. The concentration of α-ketoglutarate is dependent on the activity and metabolism within the cell along with the regulation of enzymatic activity. In E. coli citrate synthase, the enzyme involved in the condensation reaction initiating the Citric Acid Cycle is strongly inhibited by α-ketoglutarate feedback inhibition and can be inhibited by DPNH as well high concentrations of ATP.[5] This is one of the initial regulations of the α-ketoglutarate family of amino acid synthesis. The regulation of the synthesis of glutamate from α-ketoglutarate is subject to regulatory control of the Citric Acid Cycle as well as mass action dependent on the concentrations of reactants involved due to the reversible nature of the transamination and glutamate dehydrogenase reactions.[5] The conversion of glutamate to glutamine is ...
With reductions in crude protein (CP) levels and higher supplementation of crystalline essential amino acids (EAA) in swine diets, the supply of non-essential amino acids (NEAA), or nitrogen (N) required for the synthesis of NEAA, is also reduced increasing the ratio between EAA-N and total N in the diet. When diets are deficient in NEAA-N, non-protein N (NPN) could supply additional N required for the endogenous synthesis of NEAA. The main objective of the present thesis was to assess the efficiency of ammonia for providing extra N when diets are deficient in NEAA-N. Secondary objectives were to determine the effects of ammonia supplementation on the amino acid (AA) profile of retained protein as an indicator of AA requirements and quantification of ammonia absorption and metabolism in the portal-drained viscera (PDV) and liver. Added ammonia to a NEAA-N deficient diet increased body weight (BW) gain and N retention and rendered similar efficiencies as supplemented Glu and a mix of NEAA ...

Serum amino acid profiling reveals a pattern of disturbed urea cycle function in Addisons patients. Amino acid (A) arginine (ARG), ornithine (ORN) and citrulli
L-Arginine was discovered back in 1886. It reportedly came from the extract of a lowly bean. Arginine is an amino acid that can be made in the human body, otherwise known as a non-essential amino acid. A non-essential amino acid is called non-essential because it is one that can be made by the human body and so is not essential to the human diet. There are 11 nonessential amino acids: arginine, alanine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, and tyrosine. There are also essential amino acids. These are amino acids that cannot be made by the body. As a result, they must come from food.. Arginine is commonly found in many protein-rich foods. A few arginine-rich foods include steak, turkey, chicken, pork, pumpkin seeds and soy products. In researching this article I also found out on www.nutritiondata.self.com, that sea lion is incredibly high in arginine, but unless your an Eskimo, I doubt thats an actual menu choice. The average American diet ...
Package Labelling for Amino Acids: The United States Food & Drug Administration (USFDA) as per its directive [21 CFR 101.36(b)(2)(i)] stipulates that a dietary supplement containing amino acids must be labelled as such and the amino acid profile should be clearly displayed on the display panel of the package. Moreover, it should not be labeled as a protein if only amino acids are present.. How is the Amino Acid Profile Determined?. Determination of the amino acid profile of proteins and peptides present in many types of samples, including food samples like dietary supplements, is a fundamental biochemical technique. The number of free amino acids, as well as amino acids released from proteins and peptides, can be quantitated by the procedure of amino acid analysis. Generally, UV spectrophotometry and high-pressure liquid chromatography (HPLC) are used for determination of the amino acid profile of samples. This is done following good laboratory practices (GLP) in specialized laboratories with ...

Amino acids are classified into two groups, essential and non-essential amino acids. Essential amino acids (BCAA, branched chained amino acids) means the body cannot naturally produce these acids but are typically found in nutritional supplements or in the foods we eat. Non-essential amino acids are acids that are naturally produced by the body(hormones from thyroid…
Researchers tested a new amino acid supplement energy bar enriched with L-leucine to investigate if this could improve protein and energy intake in older women.
Protein makes up the structure of all cells and tissues in the body, including muscle tissue, internal organs, tendons, skin, hair and nails.. Amino acids are the building blocks of protein and there are 20 of them. 12 of these can be made in the body and so are referred to as non-essential amino acids, while the other 8 are known as essential amino acids (as they must be sourced from the diet).. Glutamine is a non-essential amino acid and is the most abundant free amino acid in muscle cells.. This L-Glutamine food supplement is sourced from fermented glucose.. ...
Our body does not come with a guarantee. Just because we are designed to synthesize and metabolize non-essential amino acids, does not mean everyone is able to. Every system, no matter how well designed can suffer from flaws, and human body is not an exception. Metabolic flaws have major impact on how our body uses nutrients and facilitates the function of cells, tissues and organs. They are dispersed with lottery like odds. But instead of winning thousands of dollars, metabolic lottery costs the sufferers thousands of dollars in therapies that help them live until the cure is found.. There are unlucky few born with major errors in non-essential amino acid metabolism. There are no rules. That can be our mother, sister, father, child, a neighbor, stranger crossing a street, anyone. And while we enjoy our steaks, live, run, laugh and take our health for granted, they have to struggle every day to survive. And they would give anything to switch places.. So what prevents them? The inborn pre-exiting ...
If youve been following along then by now youve figured out that science has proven that even less than half a gram of protein per pound of bodyweight per day is enough to both retain and build muscle mass. Today Id like to look into amino acids to see what we can learn and also to see if I can wrap this series up.. Obviously, the important component of the protein seems to be the essential amino acid content. It is now clear that muscle anabolism occurs with ingestion of only the essential amino acids meaning the non-essential amino acids are unnecessary to stimulate muscle growth following exercise(1). However, this doesnt mean that essential amino acid supplements are superior to non-essential or to whole proteins. It simply means that essential amino acids can stimulate muscle protein synthesis and there are ample non-essentials to support the elevated levels of synthesis.. Leucine may be the most important amino acid for stimulation of muscle protein synthesis. Leucine, along with ...
Amino acids can be classified according to various structural and functional properties. The classification into proteinogenic and non-proteinogenic amino acids is of essential importance in the life sciences. The former are structurally characterized by having a C-α-atom which is bound to a carboxy group, an amino group and an organic side chain R. In total, 22 different proteinogenic amino acids are known, including selenocysteine and pyrrolysine. While selenocysteine (Sec) occurs in different eukaryotic enzymes, for example in glutathione peroxidase, pyrrolysine (N6-[(2R,3R)-3-methyl-3,4-dihydro-2H-pyrrol-2-yl-carbonyl]-L-lysine) was only found in methanogenic bacteria as yet. 21 of the 22 proteinogenic amino acids are chiral with the exception of glycine where the side chain is substituted by an H atom. Accordingly, members of the former group can exist in two enantiomeric forms referred to as L- and D-isomers. The D-configuration, for example, is found in bacterial cell walls while in ...
Amino acids refer to the molecular structure consisting of both amine and carboxyl functional groups. Referred to as alpha-amino acids in Biochemistry, typically it is defined with the formula H2NCHRCOOH where R stands for organic substitute. Amino acids can be called as the building blocks of our life.. They get combined in an unlimited number of configurations to construct all the required proteins with which our body is built. There are essentially 20 common amino acids that keep us alive, healthy and energetic. If deficiency occurs in an individual amino acid, it may create serious problem to our health system. The name of these 20 common amino acids is as follows: alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalaine, proline, serine, threonine, tryptophan, tyrosine, and valine.. Alanine. It is one of the most significant among the 20 common amino acids. It offers energy to your system. It ...

The 20 amino acids involved in protein biosynthesis are divided into two broad groups, essential and non-essential. For good health, eight of these amino acids are essential and must be taken either in the form of pill or capsule, in addition to the minuscule amounts found in the food we eat. The remaining 12 non-essential amino acids,the body can synthesize from the diet. For example, Betamine is a non-essential amino acid. It is found in beetroot. When the tuber is included in the diet, the body uses the Betamine in it for the production of Dopamine. People suffering from Parkinson and those who are not, are advised to include beetroot frequently in the diet.. ...
Excess alcohol consumption is a top risk factor for death and disability. Fatty liver will likely develop and the risk of liver disease increases. We have previously demonstrated that an essential amino acid supplement (EAAS) improved protein synthesis and reduced intrahepatic lipid in the elderly. The purpose of this study was to further evaluate the influence of EAAS on intrahepatic lipid (IHL), body composition, and blood lipids in individuals with mild to moderate alcohol use disorder (AUD). Following consent, determination of eligibility, and medical screening, 25 participants (18 males at 38±15 years/age and 7 females at 34±18 years/age) were enrolled and randomly assigned to one of two dosages: a low dose (LD: 8 grams of EAAS twice/day (BID)) or high dose (HD: 13 grams of EAAS BID). Both groups consumed the supplement for 4 weeks. Pre- and post-EAAS administration, IHL was determined using magnetic resonance imaging/spectroscopy, body composition was analyzed using dual energy x-ray

In the new study, the researchers gave middle-aged, male mice extra branched-chain amino acids (BCAA) in their drinking water. The animals were otherwise healthy and eating standard mouse chow.. Animals that were given the extra amino acids over a period of months lived longer, with a median life span of 869 days compared to 774 days for untreated control animals, the researchers report. Thats an increase of 12 percent.. Those survival gains were accompanied by an increase in mitochondria in cardiac and skeletal muscles. Mitochondria are the cellular components responsible for powering cells. The supplement-fed mice also showed increased activity of SIRT1, a well-known longevity gene, and of the defense system that combats free radicals. They therefore showed fewer signs of oxidative damage.. The benefits of the amino acid supplements appear similar to those earlier ascribed to calorie restriction, Nisoli said.. Treated animals also showed improvements in their exercise endurance and in motor ...

Using high performance liquid chromatographic method, for the first time, this study determined the concentrations of 17 serum amino acids of the Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis) in Tian-e-zhou Baiji Nature Reserve and the Baiji Dolphinarium of Institute of Hydrobiology, Chinese Academy of Sciences. The results showed that the mean concentrations of 14 serum amino acids (Aspartic acid Asp, Glutamic acid Glu, Serine Ser, Arginine Arg, Glycine Gly, Threonine Thr, Alanine Ala, Isoleucine Ile, Leucine Leu, Phenylalanine Phe, Valine Val, Lysine Lys, Tyrosine Tyr and Cysteine Cys) of captive porpoises were significantly higher (p < 0.0001 or 0.05) than those of free-ranging animals, except for Proline Pro, Methionine Met and Histidine His. No significant differences of serum amino acid concentrations were noted between genders and between mature and immature free ranging Yangtze finless porpoises. Glu of captive Yangtze finless porpoise was the highest, then was the ...
Since your body cannot produce essential amino acids, they must be provided through your diet.. Fortunately, many foods are rich in essential amino acids, making it easy to meet your daily needs.. The US recommended daily allowances per 2.2 pounds (1 kg) of body weight for the nine essential amino acids are:. Histidine: 14 mg. Isoleucine: 19 mg. Leucine: 42 mg. Lysine: 38 mg. Methionine (+ the non-essential amino acid cysteine): 19 mg. Phenylalanine (+ the non-essential amino acid tyrosine): 33 mg. Threonine: 20 mg. Tryptophan: 5 mg. Valine: 24 mg. Foods that contain all nine essential amino acids are referred to as complete proteins.. Complete protein sources include:. Meat. Seafood. Poultry. Eggs. Dairy Products. Soy, quinoa and buckwheat are plant-based foods that contain all nine essential amino acids, making them complete protein sources as well. Other plant- based sources of protein like beans and nuts are considered incomplete, as they lack one or more of the essential amino acids. ...

Mars is a CO2-abundant planet, whereas early Earth is thought to be also CO2-abundant. In addition, water was also discovered on Mars in 2008. From the facts and theory, we assumed that soda fountains were present on both planets, and this affected amino acid synthesis. Here, using a supercritical CO2/liquid H2O (10:1) system which mimicked crust soda fountains, we demonstrate production of amino acids from hydroxylamine (nitrogen source) and keto acids (oxylic acid sources). In this research, several amino acids were detected with an amino acid analyzer. Moreover, alanine polymers were detected with LC-MS. Our research lights up a new pathway in the study of lifes origin.
[Objective] The research aimed to study the amino acids and mineral elements contents of Chengdu Ma goat.[Method] A completely ranomized design involving a 2×2×3 factorial arrangement at different ages(adult,one-year old),gender(male,female) and anatomical regions(longissmus dorsi muscle,biceps femoris muscle,psoas major muscle) was designed.And amino acids and mineral elements contents were analyzed.[Result] The results showed that the contents of mean total amino acid,adult essential amino acid,and baby essential amino acid were(21.41±1.93),(9.27±0.89) and(10.74±1.02)mg/100 mg respectively.The contents of examined 17 amino acids were affected by age,gender,and anatomical regions.Except threonine,the contents of all examined amino acids tasty amino acids contents(P0.05),and total amino acid contents(P0.01) were affected by age greatly,and the adult Ma goat was larger.The total amino acid content and adult essential amino acid content were affected by gender(P0.05) and anatomical regions(P0.05)
Our bodies need protein, which comes from both essential and non-essential amino acids highlighted here.. The body produces non-essential amino acids, but the 9 essential amino acids: Histidine, Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Threonine, Tryptophan, and Valine, must come from food sources. It is important for vegans to take note of the essential amino acids they are getting daily from their diet and make an effort to achieve the standard for the Recommended Daily Intake (RDI). There are numerous options for vegans other than proteins from animals but it is necessary that an effort is put into what you eat, when you eat it and what benefits you are getting from what you are eating. Here is a resource for the nutritional content on numerous food items. (Note: It sometimes converts to grams so you may have to do your own metric/imperial conversion.). The FDA recommends that 10% to 35% of daily calories come from protein. This roughly translates to .40 to .50 grams of protein ...
The effects of dexamethasone on nitrogen and amino acid metabolism in the dog were studied in order to gain insight into the role of glucocorticoids in accelerated proteolysis and altered metabolism of glutamine in catabolic illnesses. After dexamethasone administration at a dose of 0.44 mg X day-1 X kg-1, nitrogen balance shifted from slightly positive (+0.126 g N X day-1 X kg-1) to markedly negative (-0.278 g N X day-1 X kg-1). This was associated with a 23% fall in total free amino acid nitrogen in skeletal muscle, with 80% of the decline accounted for by a decrease in glutamine. Plasma glutamine concentration decreased by 26%, although total plasma free amino acid nitrogen was unchanged because of a 49% increase in alanine. The alterations in intracellular and circulating levels of glutamine were not accompanied by measurable changes in glutamine synthetase or glutaminase activities in skeletal muscle. Hindquarter amino acid flux measurements demonstrated that the decline in intracellular ...
1. A double-lumen perfusion technique has been used in man to study jejunal absorption of individual amino acids from an amino acid mixture simulating casein, and a tryptic hydrolysate of casein consisting of oligopeptides and amino acids.. 2. Total absorption was greater from the tryptic hydrolysate than from the amino acid mixture. There was wide variation in the extent to which individual amino acids were absorbed from the amino acid mixture. This was decreased when the tryptic hydrolysate was perfused. Amino acids which were particularly poorly absorbed from the amino acid mixture were absorbed to a substantially greater extent from the tryptic hydrolysate.. 3. The results suggest that the characteristics of absorption of amino acid mixtures do not represent those of absorption of the physiological products of intraluminal digestion, oligopeptides and amino acids.. ...
An abundant supply of amino acids enhances the metabolic effect of exercise on muscle protein. Am. J. Physiol. 273 (Endocrinol. Metab. 36): El22-E129, 1997. -Six normal untrained men were studied during the intravenous infusion of a balanced amino acid mixture (-0.15 g. kg-l. h-l for 3 h) at rest and after a leg resistance exercise routine to test the influence of exercise on the regulation of muscle protein kinetics by hyperaminoacidemia. Leg muscle protein kinetics and transport of selected amino acids (alanine, phenylalanine, leucine, and lysine) were isotopically determined using a model based on arteriovenous blood samples and muscle biopsy. The intravenous amino acid infusion resulted in comparable increases in arterial amino acid concentrations at rest and after exercise, whereas leg blood flow was 64 +/- 5% greater after exercise than at rest.

The event, themed The Value Chain of Phytate Destruction, has seen feed and nutrition experts from around the world share the latest research into how combatting phytate can improve feed efficiency, nutrient utilisation, sustainability and ultimately profitability.. On the final day, Professor Hank Classen, University of Saskatchewan, highlighted the impact of phytate and phytate esters on protein digestibility and the influence of superdoses of phytase on amino acid digestibility, specifically non-essential amino acids.. The use of high levels of phytase is promising in young birds because we did see a more consistent response in phytate hydrolysis and so the availability of amino acids and energy is also more predictable.. Professor Layi Adeola of Purdue University discussed the fate of amino acids in the gastrointestinal tract, a very complex system of endogenous enzymes and transporters.. This research was followed by that of Dr Sami Dridi, University of Arkansas, and Dr Gabriel Morales, ...
We established that Caulobacter senses the repletion of intracellular tryptophan due to the HipA2 phosphorylation of TrpS which, in turn, inhibits glutamine synthesis by stimulating GlnA adenylylation (Fig. 4). Why does the cell choose tryptophan? A quantification of absolute metabolite concentrations in E. coli revealed that tryptophan was the least abundant amino acid in the cell (41), which might represent a general fact in bacteria. Manipulating the intracellular levels of a less abundant amino acid might be easier to achieve and does not require a higher energy cost. The accumulation of tryptophan due to the disrupted aminoacylation of tRNATrp is likely due to the insensitivity of trp operon repressor protein to increased levels of free tryptophan in Caulobacter (42). It is known that in E. coli tryptophan synthesis is regulated by a trp operon, which is turned on for tryptophan synthesis when tryptophan levels are low and turned off when tryptophan levels are high (43). This feedback ...
Branched chain amino acids have been a supplement staple for bodybuilders for many years. Why they are used so much is because of their anti-catabolic and energy producing effects. BCAAs consist of leucine, isoleucine, and valine. These three are known as essential amino acids. Essential amino acids are not produced in the body, therefore must be obtained by proper nutritional support. Non-essential amino acids are produced in the body. Supplementing with BCAAs will help ensure that the athlete is supplying the body with an adequate amount of essential amino acids. BCAAs differ than other amino acids in that they are metabolized in the muscle and not the liver like other amino acids are. BCAAs can produce a boost in energy during intense training. BCAAs can help improve blood plasma and serum markers, which help improve the recovery time of damaged tissue. During intense training leucine is easily depleted and contributes to tissue fatigue. Keeping BCAAs high in the bloodstream after an ...
Problem statement: The literature is reviewed and supports a strong anecdotal relationship between bromocriptine use and psychosis. It is well known that any interference with brain amino acid levels is likely to lead to disorder. Our previous research has shown that bromocriptine produced significant changes in the heart and kidneys amino acid contents. It has been confirmed that the brain amino acids concentrations are influenced by plasma amino acid levels. Therefore, it is the thought of interest to investigate the effect of bromocriptine, sulpiride or their combination on the brain and plasma amino acid concentrations of rat. Approach: The influence of chronic treatment with bromocriptine 20 mg kg day-1 i.p, sulpiride 20 mg kg day-1 i.p. or their combination bromocriptine 20 mg kg day-1 i.p + sulpiride 20 mg kg day-1 i.p. for 6 weeks on free amino acids in the brain and the plasma of rats were carried out. The amino acids were quantified using the LKB 4400 Amino Acid Analyzer and the Hami1tons

Glycine (symbol Gly or G;[5] /ˈɡlaɪsiːn/)[6] is an amino acid that has a single hydrogen atom as its side chain. It is the simplest amino acid (since carbamic acid is unstable), with the chemical formula NH2‐CH2‐COOH. Glycine is one of the proteinogenic amino acids. It is encoded by all the codons starting with GG (GGU, GGC, GGA, GGG). Glycine is integral to the formation of alpha-helices in secondary protein structure due to its compact form. For the same reason, it is the most abundant amino acid in collagen triple-helices. Glycine is also an inhibitory neurotransmitter - interference with its release within the spinal cord (such as during a Clostridium tetani infection) can cause spastic paralysis due to uninhibited muscle contraction. Glycine is a colorless, sweet-tasting crystalline solid. It is the only achiral proteinogenic amino acid. It can fit into hydrophilic or hydrophobic environments, due to its minimal side chain of only one hydrogen atom. The acyl radical is glycyl. ...

Considering the limited knowledge on the effects of dietary amino acid intake on dysglycemia, we assessed the possible association of dietary protein and amino acid patterns with the risk of pre-diabetes in a prospective population-based study. Participants without diabetes and pre-diabetes (n = 1878) were recruited from the Tehran Lipid and Glucose Study and were followed for a mean of 5.8 years. Their dietary protein and amino acid intakes were assessed at baseline (2006-2008); demographic, lifestyle, and biochemical variables were evaluated at baseline and in follow-up examinations. Pre-diabetes was defined according to the American Diabetes Association criteria. Multivariate Cox proportional hazard regression models, adjusted for potential confounders, were used to estimate the risk of pre-diabetes across tertiles of dietary protein and amino acid pattern scores. The mean age of the participants (44.9% men) was 38.3 ± 12.7 years at baseline. Three major amino acid patterns were characterized: (1)
In contrast to the specific signs that may occur as a result of vitamin or mineral deficiencies, the effects of essential amino acid deficiencies are nonspecific: reduced growth, reduced feed consumption, decreased egg production and egg size, and loss of body weight in adult hens. The decreased of feed intake occurs within hours of consumption of a deficient diet and is due to a distortion in plasma and tissue amino acid levels.. Practical ingredients usually are limiting in one or more amino acids. It is often cost effective to supply the limiting amino acids in the form of synthetic amino acids, especially lysine and methionine. Other amino acids such as threonine, tryptophan, arginine, and isoleucine can become limiting when unusual protein sources are used or when the dietary protein level is reduce. Diets that are devoid of animal by-products are often fortified heavily with feed-grade amino acids.. Unlike severe deficiencies, marginal amino acid deficiencies often result in increased food ...
Alanine at position 294 (Ala294) within the motif 3 consensus of Escherichia coli phenylalanyl-tRNA synthetase alpha subunit has previously been implicated as a determinant of amino acid specificity. To characterize the role of Ala294, the catalytic effects of amino acid replacements at this position were tested with purified wild-type and mutant phenylalanyl-tRNA synthetases. We show that Ala294 is involved in amino acid binding and that it influences specificity as a determinant of binding pocket size. Replacement of Ala294 by either glycine or serine, thereby increasing or decreasing the size of the binding pocket, respectively, reduces affinity for phenylalanine. The Gly294 mutant shows a relaxed specificity toward synthetic para-halogenated phenylalanine analogues, the apparent dissociation constant Km increasing in direct relation to an increase of the van der Waals radius of the para group, thus confirming the role of position 294 in determining amino acid binding pocket size.

Proline is a non-polar proteinogenic amino acid that forms a tertiary amide when incorporated into peptides. It does not have a hydrogen on the amide group and therefore cannot act as a hydrogen bond donor. Proline is known as a classical breaker of both the α-helical and β-sheet structures in proteins and peptides. Nevertheless, it is widely distributed in the putative transmembrane domains of many protein transporters and channels, regions believed to be α-helical.1. Among the proteinogenic amino acids, proline plays a special role. In protein structures the planar peptide bond occurs predominantly in the trans conformation.2 The proline residue restricts the conformational space of the peptide chain. However, due to the small free enthalpy difference between the cis and trans Xaa-Pro bond isomers of 2.0 kJ·mol-1 (compared to 10.0 kJ·mol-1 for other Xaa-non-Pro peptide bonds), there is a relatively high intrinsic probability of 30% cis conformation at RT and both cis and trans isomers are ...

The moisture,crude ash,crude protein,crude fat,polysaccharide,amino acids,fatty acids and minerals were determined by national standard nutritional method. The results showed as follows: the moisture of wild and cultured Sepia pharaons squid ink was not significantly different( P 0. 05),whereas other basic nutrient contents( dry weight basis) were significantly different( P 0. 05). The content of polysaccharide was abundant and in wild squid ink( 3. 25%) in cultured squid ink( 3. 98%). Two kinds of squid ink contained 7 kinds of essential amino acids,10 kinds of non-essential amino acids and 9 kinds of medicinal amino acids,with wild squid ink essential amino acids( 3. 24%) with cultured squid ink( 3. 32%); and wild squid ink medicinal amino acids( 5. 86%) cultured squid ink( 6. 23%),accounting for 56. 78%,65. 71% of total amino acids
OBJECTIVE Our aim was to investigate the relationship between imbalances of plasma amino acids and pain in chronic pancreatitis (CP). METHODS Thirty patients with alcoholic CP in an exocrine-insufficient state were examined. We divided them between diet and control group. Diet group ingested 80 g/300 kcal of the elemental diet Elental®. This diet of 300 kcal/day was administered for two months. Selected clinical and laboratory values were compared between both groups before and after diet. Pain was observed and compared using a visual analog scale (VAS). RESULTS There was no significant difference in the BMI between both groups before and after diet. The serum albumin level in diet group after diet was significantly higher than in control group (P=0.036). There was no significant difference in HbA1c between both groups before and after diet. The total amino acid concentration was significantly higher in diet group after diet than in control group (P=0.033). The concentrations of serum histidine

Nutrition Facts: Amino acids are the building blocks of protein. Protein has an important job in building and rebuilding body tissue and providing the body with nitrogen, an essential element for all living beings. There are both essential and nonessential amino acids. Essential amino acids must be obtained from the diet; nonessential amino acids are made by the body. Here are lists of the essential and nonessential amino acids:
Alpha globulins are serum proteins that have the most rapid migration during electrophoresis. This subgroup of globulins is divided into faster and slower alpha1 and alpha2-globulins.Proteins are the most abundant compounds in your serum. Amino acids are the building blocks of all proteins. In turn proteins are the building blocks of all cells and body tissues. They are the basic components of enzymes, many hormones, antibodies and clotting agents. Proteins act as transport substances for hormones, vitamins, minerals, lipids and other materials. In addition, proteins help balance the osmotic pressure of the blood and tissue.Medical Tests Analyzer labtest bloodtest What does the test result mean?
Ingestion of protein or intravenous infusion of amino acids acutely elevates glomerular filtration rate (GFR) and renal plasma flow (RPF) by unknown mechanisms. Endothelium-derived relaxing factor (EDRF), now known to be nitric oxide derived from metabolism of L-arginine, participates in local regulation of vascular tone. To investigate the hypothesis that EDRF may participate in the renal vasodilatation and increased GFR after amino acid infusion, we characterized the effect of inhibition of EDRF synthesis with NG-monomethyl L-arginine (LNMMA) on basal renal hemodynamics and the response to infusion of a 10% mixed amino acid solution (1 ml/hr i.v.) in the rat. Renal arterial infusion of LNMMA (500 micrograms/kg/min) resulted in a significant increase in mean arterial pressure, decreases in GFR (20%) and RPF (44%), and a significant increase in filtration fraction. Pretreatment with the angiotensin II receptor antagonist Sar-Gly-angiotensin II did not prevent the increase in blood pressure but ...
Synthesis of total RNA, DNA, and protein was followed in a haploid yeast auxotroph during starvation for required amino acids and uracil, and during shift-up and shift-down conditions. During amino acid starvation, synthesis of macromolecular constituents was not immediately affected, reflecting the presence of large intracellular amino acid pools. Under conditions in which there was no net RNA and protein synthesis (amino acid and uracil starvation), total DNA continued to be synthesized for a total increase of 10-15%. The results suggested that cells engaged in DNA synthesis at the introduction of starvation conditions complete replication of the genome but do not initiate new periods of DNA synthesis. Upon return of a starved culture to complete medium, a period of DNA synthesis was required before the culture began to divide at the rate characteristic for complete medium. Compounds which are known to inhibit DNA synthesis in bacteria had no effect upon starved yeast cultures returned to ...

Many protein and amino acid supplements are touted as being able to maximize the gains achieved from resistance exercise by preventing muscle protein catabolism and stimulating anabolism. If effective, such supplements would be useful not only for athletes and for those trying to increase their fat free mass, but also for patients recovering from injuries or burns and for the prevention of aging-associated muscle loss. It has been shown that intravenous infusion or oral administration of complete mixtures of amino acids has a positive effect on muscle protein synthesis and net muscle anabolism following exercise. Since nonessential amino acids are synthesized by the body in response to resistance exercise, administration of essential amino acids only following exercise has the same positive anabolic effect on muscle as complete amino acid supplementation. Furthermore, oral administration of whole proteins following training has a similar anabolic effect, as whole proteins such as whey and casein ...

The metabolic effects of selected and branched-chain amino acid (BCAA)-enriched parenteral solutions were studied in liver cirrhosis. After 3 days of an oral protein-free diet with balanced amino acid (AA) infusion, 36 cirrhotic patients without encephalopathy were randomly divided into four groups. Groups A and B were infused for 5 days with BCAA (valine, leucine, isoleucine) at doses of 0.5 and 1.0 g/kg/day, respectively, as the only nitrogen source. Group C received 0.8 g/kg of essential and nonessential AA solution with a prevalence of BCAA; the last group (D) continued the basic standard diet, as control. Routine chemistry, urinary nitrogen losses, nitrogen balance, and the whole plasma AA pattern were detected before and after the treatment period. BCAA alone led to an impressive and significant improvement in the basic AA pattern in both the A and B groups. The same results were obtained in group C for plasma AA. In particular, the ratio of BCAA to aromatic amino acids in groups A, B, and ...

Bread has been eaten since ancient times and is baked by heating with dry air, steam, or oil in conventional ovens, stone ovens, tandoors, or other baking devices. Bread samples in this study were baked in a traditional stone oven at various temperatures, and the chemical composition and allergic activity were analyzed. The free amino acid content decreased with increasing baking temperature, Pro, Ala, Val, Arg, and Glu being predominant. Proteins in the stone oven bread were converted to lower-molecular-weight molecules, particularly those in the 15-16 kD and 31-37 kDa bands, resulting in decreased allergens with increasing baking temperature..

The synthesis and interactions of the d- and l-enantiomers of the amino acid amide derivatives [Formula: see text] (I) and lysyl dipeptides [Formula: see text] (II) with poly rI·poly rC, poly rA·poly rU and calf thymus DNA is reported. The following results were found. (1) The degree of stabilization of the helices as measured by the Tm (melting temperature) of the helix-coil transition was dependent on the nature of the amino acid. (2) For the poly rI·poly rC helix, the l-enantiomers of salts (I) and (II) stabilized more than the d-enantiomers. The same was true for calf thymus DNA in the presence of salts (II) and for poly rA·poly rU in the presence of salts (II) and the proline derivatives of salts (I). (3) As R increased in size and became more apolar, the amount of stabilization of the poly rI·poly rC helix in the presence of salts (I) decreased. On the other hand, the amount of stabilization increased with more polar substituents. An attempt was then made to determine whether the ...
Amino acids are the building blocks of protein. Branched chain amino acids - made up of Leucine, Isoleucine and Valine - comprise approximately 35% of the amino acid composition of muscle tissue. Branched chain amino acids (BCAAs) have attracted a lot of interest in body building and strength based sports because they are the only amino acids that are actually metabolised in the muscle. BCAAs are converted into two other amino acids - glutamine and alanine - which are released in large quantities during intense aerobic exercise. They can also be used directly by the muscles, particularly when muscle glycogen is depleted.
