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...

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 ...

synthesis and characterization of two functionalized gold nanoparticles by using of two poly functional amino acids (l-arginine and l-aspartic acid) are reported. the gold nanoparticles were reduced by sodium citrate and functionalized with l-arginine at the ph of 7 and 11 and l-aspartic acid at the ph of 7. transmission electron microscopy, uv-vis spectroscopy, dynamic light scattering, zeta p...

The observation that Leuconostoc dextranicum 8086 requires either aspartic acid or threonine for growth resulted in studies in which a ri%e’ of aspartic acid in the biosynthesis of threonine was demonstrated in certain lactobacilli (1). In the present investigation, the nature of the requirement for either aspartic acid or threonine for growth of L. dextranicum 8086 has been found to be the res...

The aim of the present study is to quantify the amount of aspartic acid in Coccinia indica crude drug, lab extract and commercial extract by HPTLC method. The stationary phase was precoated aluminium silica gel G F 254 Plates. The mobile phase for aspartic acid was n-Butanol: Glacial acetic Acid: Water (50: 10: 40). The methanolic solution of standard aspartic acid (1 mg/ ml concentration) 5 μl...

Synthesis and characterization of two functionalized gold nanoparticles by using of two poly functional amino acids (L-Arginine and L-Aspartic acid) are reported. The gold nanoparticles were reduced by sodium citrate and functionalized with L-Arginine at the pH of 7 and 11 and L-Aspartic acid at the pH of 7. Transmission electron microscopy, UV-Vis spectroscopy, dynamic light scattering, zeta p...

Aspartic acid, like glutamic acid, occupies a central position in amino acid metabolism. In most tissues it takes part in the transamination reaction (1). In the liver and the kidney, where all amino acids undergo cleamination, the rate of this process for aspartic acid is second only to glutamic acid (2). For these reasons, one would expect the exchange of amino nitrogen of aspartic acid with ...

The experiments with isotopes of the group at the Carnegie Institution of Washington laboratory (1) led to the concept of the aspartic acid family of amino acids. It was shown that, in Escherichiu co.%, aspartic acid contributes carbon to form all or part of the carbon skeleton of threonine, methionine, isoleucine, lysine, and diaminopimelic acid. The intermediates in the transformation of aspa...
