The conversion of L-glutamate to D-glutamate by glutamate racemase (GR) enzyme is an essential step in the synthesis of peptidoglycan.There are two forms of glutamic acid found in nature: L-glutamic acid and D-glutamic acid. D-glutamic acid, is not endogenously produced in higher mammals. It is found naturally primarily in the cell walls of certain bacteria. D-glutamate is also present in certain foods e.g., soybeans and also arises from the turnover of the intestinal tract microflora, whose cell walls contain significant D-glutamate. Unlike other D-amino acids, D-glutamate is not oxidized by the D-amino acid oxidases, and therefore this detoxification pathway is not available for handling D-glutamate.COAItem Assay99.0~101.0%98.5~101.5%Sulfate(SO4)≤0.02%≤0.04%Iron(Fe)≤10ppm≤30ppmHeavy metals(Pb)≤10ppm≤15ppmArsenic≤1ppm(As2O3)≤1.5ppm(As2O3)Loss on drying≤0.20%≤0.30%Residue on ignition≤0.10%≤0.40%FUNCTIOND-Glutamic Acid is the unnatural (R)-enantiomer of Glutamic Acid, a non-essential amino acid. Its salt form (glutamate) is an important neurotransmitter that plays a key role in long-term potentiation and is important for learning and memory. Glutamic Acid is also a key molecule in cellular metabolism.
