Abstract:
Aspartic acid is an amino acid present in the modern proteins, however, is considered a primitive amino acid hence its importance in prebiotic chemistry experiments studies. In some works of prebiotic chemistry have been studied the synthesis and the stability of organic matter under high energy sources, and the role of clays has been highlighted due to clays that can affect the reaction mechanisms in the radiolytic processes. The present work is focused on the study of the role of Namontmorillonite in the gamma radiolysis processes of L-aspartic acid. Gamma radiolysis processes were carried o

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

Experiments to investigate the metabolism of glycine, L-glutamic acid and L-aspartic acid by Moniliformis moniliformis were carried out by incubating adult worms aerobically for 3 h at 37°C in Tyrode's solution containing either [U-14C]glycine, L-[U-14C]glutamic acid, L-[U-14C]aspartic acid or L-[4-14C]aspartic acid. Much of the glycine and glutamic acid was absorbed by the worms, but little of either was metabolized. Aspartic acid was readily taken up and metabolized.

Abstract:
Abstract Aspartic acid is a neurotransmitter in the central nervous system that acts via the glutamate receptor and the analogue, N-methyl-d,l-aspartic acid (NMA) is an agonist that stimulates GnRH secretion. Under normal dietary conditions, the plasma concentration of aspartic acid in ewes is low and if increased by improved nutrition may increase the brain concentration of aspartic acid leading to increased gonadotrophin secretion. In two experiments we investigated the effects of NMA on pituitary hormone concentrations and the effects of aspartic acid on ovulation rate and pituitary hormone

Abstract:
Voltammetric technique was used to study the binary and ternary complexes of cadmium with L-amino acids and vitamin-C (L-ascorbic acid) at pH =7.30 ± 0.01, μ = 1.0M KNO3 at 25ºC and 35ºC. Cd (II) formed 1:1:1, 1:1:2 and 1:2:1 complexes with L-lysine, L-ornithine, L-threonine, L-serine, L-phenylglycine, L-phenylalanine, L-glutamic acid and L-aspartic acid used as primary ligands and L-ascorbic acid used as secondary ligand. The trend of stability constant of complexes was Llysine &lt; L-ornithine &lt; L-threonine &lt; L-serine &lt; L-phenylglycine &lt; L-phenylalanine &lt; L-glutamic acid &lt;

Abstract:
The experiment was carried out in the Abu Al-Fadl Forest Nursery, the Plant Production Department, Al-Diwaniyah Agriculture Directorate (3 km north-east of Al-Diwaniyah city) during the winter season 2021-2022 to determine the effect of four levels of phosphate fertilizer (0, 30, 60 and 90 kg P ha-1 ) and two concentrations of aspartic acid spray (0 and 200 mg aspartic L -1 ), on the growth and yield of oats Avena sativa L. Shifa cultivar. The experiment was applied according to a Randomized Complete Block Design (RCBD) by a split plot with three replicates. The levels of phosphate fertilizer
