L-Aspartic Acid | 56-84-8

Aspartic acid (abbreviated as D-AA, Asp, or D) is an α-amino acid with the chemical formula HOOCCH(NH2)CH2COOH. The carboxylate anion and salts of aspartic acid are known as aspartate. The L-isomer of aspartate is one of the 22 proteinogenic amino acids, i.e., the building blocks of proteins. Its codons are GAU and GAC.
Aspartic acid is, together with glutamic acid, classified as an acidic amino acid with a pKa of3.9, however, in a peptide, the pKa is highly dependent on the local environment. A pKa as high as 14 is not at all uncommon. Aspartate is pervasive in biosynthesis. As with all amino acids, the presence of acid protons depends on on the residue's local chemical environment and the pH of the solution.
l-arginine l-aspartate is one of the 20 amino acids that build up protein. l-arginine l-aspartate is one of the non-essential amino acids, meaning it can be synthesised in the body.
l-arginine l-aspartate is a precursor of nitric oxide and other metabolites. It is an important component of collagen, enzymes ,skin and connective tissues. l-arginine l-aspartate plays important roles in the synthesis of various protein molecules; creatine being the most easily recognised. It may have antioxidant property and reduces accumulation of compounds such as ammonia and plasma lactate, by-products of physical exercise. It also inhibits platelet aggregation and has also been known to decrease blood pressure.
