Objective Diets high in glucose or fat contribute to an increased prevalence of the diseases. Therefore, objective current research was observe and evaluate impact dietary components on different metabolomic profiles primary tissues mice. Methods For 8 weeks, diet with high-glucose or-fat given C57BL/6 J The levels metabolites mice were studied using gas chromatography-mass spectrometry (GC-MS)...

The rate at which amino acids are removed from the blood by the organs has been previously reported (l-3). The methods used permitted only estimation of total amino acid nitrogen, and no information could be gained as to the fate of the individual amino acids injected. Quantitative paper chromatography (4) seemed to lend itself as a valuable method in studying the pattern of absorption of paren...

Three acyl derivatives of amino acids, dicarbobenzoxy-l-lysine sodium, carbobenzoxy-l-aspartic acid-beta-benzyl ester potassium, and N-3-phenylpropionyl-S-benzyl-l-cysteine potassium inhibit the growth of parainfluenza 1 (hemadsorption 2) virus. The growth of simian virus 40, vaccinia, poliomyelitis type 1, Semliki Forest, Eastern equine encephalitis, and Western equine encephalitis viruses was...

Cyanophycin (multi-L-arginyl-poly-L-aspartic acid) is a nitrogen storage polymer found in most cyanobacteria and some heterotrophic bacteria. The cyanobacterium Synechocystis sp. strain PCC 6803 accumulates cyanophycin following a transition from nitrogen-limited to nitrogen-excess conditions. Here we show that the accumulation of cyanophycin depends on the activation of the key enzyme of argin...

acid (13) has been modified to permit its application to the analysis of L-asparagine and L-aspartic acid in tissues and body fluids. The method involves a sequence of enzymic reactions which result ultimately in the oxidation of NADH. With this method it has been possible to determine the concentration of L-asparagine in various tissues, to follow the disposition of L-asparagine in animals and...

It is shown by competition experiments that tobacco cell lines have distinct transport systems for L-amino acids. For all tested amino acids the Lineweaver-Burk plots were diphasic indicating the presence of more than one carrier for any one amino acid. Moreover distinct transport systems for neutral, acidic and basic amino acids were kinetically characterized. Based on competition experiments ...

This article comprises detail information about Lasparaginase, encompassing topic such as various sources of Lasparaginase, mechanism and properties of L-asparaginase. Also describe the production, cultivation and purification of Lasparaginase along with information about the application of Lasparaginase. L-asparaginase catalyzes the conversion reaction to convert asparagine to aspartic acid an...

Two purified isozymes of protein carboxyl methyltransferase from bovine brain catalyze the substoichiometric transfer of methyl groups in vitro from S-adenosyl-L-[methyl-3H]methionine to several erythrocyte membrane proteins, which include bands 2.1, 3, and 4.1, as well as several integral membrane polypeptides. D-Aspartic acid beta-[3H]methyl ester has been isolated from proteolytic digests of...
