Risk assessment for the amino acids taurine, L-glutamine and L-arginine.

Taurine, glutamine and arginine are examples of amino acids which have become increasingly popular as ingredients in dietary supplements and functional foods and beverages. Animal and human clinical research suggests that oral supplementation of these amino acids provides additional health and/or performance benefits beyond those observed from normal intake of dietary protein. The increased con...

Pharmacokinetics of arginine and related amino acids.

Arginine (ARG) and its related amino acids (AAs) ornithine (ORN) and citrulline (CIT) find a range of applications as dietary supplements in subgroups of healthy subjects (e.g., bodybuilders) and patients with acute or chronic malnutrition. These AAs appear to be well utilized in humans with, in general, a rapid return of blood concentrations to basal values (i.e., within 5-8 h) and low absolut...

Metabolism of basic amino acids in Pseudomonas putida. Intermediates in L-arginine catabolism.

y-Guanidinobutyrate amidinohydrolase, the third enzyme of L-arginine catabolism in Pseudomonas putida, has been purified 6%fold from extracts of cultures grown on L-arginine. Synthesis of the amidinohydrolase is induced by growth on L-arginine or y-guanidinobutyrate, but not by growth on y-aminobutyrate or on urea plus DL-malate. Hydrolysis of y-guanidinobutyrate to y-aminobutyrate and urea pro...

Theoretical Thermodynamic Study of Arginine and Lysine Amino Acids at different Solvents

The thermodynamic functions such as enthalpy, H°, Gibbs free energy, G°, and entropy, S°, of Arginine and Lysine amino acids were theoretically studied at different polar solvents by using ²Gaussian o3², software. First, the structural optimization of isolated Arginine and Lysine were done in the gas phase by applying the Density Functional Theory (B3LYP) level ...
