the aim of this study was to evaluate the effect of d-aspartic acid on semen characteristics of ross 308 roosters. thirty 60-wk-old ross 308 roosters were randomly assigned into 6 groups and individually caged. all groups fed the same basal diet and orally administered with different levels of d-aspartic acid: 0(a-0), 40 (a-40), 80 (a-80), 120 (a-120), 160 (a-160), and 200 (a-200) mg/kg bw per ...

Aspartic acid, or “aspartate,” is a non-essential, four carbon amino acid produced and used by the body in two enantiomeric forms: L-aspartic D-aspartic acid. The L-configuration of acids dominant form protein synthesis; thus, far more common configuration. However, one only known D-amino biosynthesized eukaryotes. While biosynthesis neurotransmission, associated with neurogenesis endocrine sys...

Interaction between aspartic acid and D-glucose, D-galactose, and D-fructose has been studied by isothermal titration calorimetry, calorimetry of dissolution, and densimetry. It has been found that D-glucose and D-fructose form thermodynamically stable associates with aspartic acid, in contrast to D-galactose. The selectivity in the interaction of aspartic acid with monosaccharides is affected ...

BACKGROUND Although abundant research has investigated the hormonal effects of d-aspartic acid in rat models, to date there is limited research on humans. Previous research has demonstrated increased total testosterone levels in sedentary men and no significant changes in hormonal levels in resistance trained men. It was hypothesised that a higher dosage may be required for experienced lifters,...

equilibria of the reaction of molybdenum(vi) with l-aspartic acid (asp) and l- glutamic acid(glu) have been studied by spectrophotometric measurements in mixed solvent systems at an ionicstrength of 0.2 mol/dm3 sodium perchlorate, employed (15, 20, 25, 30± 0.1°c) at ph ranges of 3.2to 5.5 with a high ratio of ligand to metal. the stability constants of the complexes and theresulting free energy...
