D-Aspartic Acid | 1783-96-6

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 of 3.9, 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 the residue's local chemical environment and the pH of the solution.
Aspartic acid is a type of amino acid. Amino acids are used as building blocks to make protein in the body. One type of aspartic acid, called D-aspartic acid, is not used to make protein, but it is used in other body functions. Aspartic acid is an α-amino acid that is used in the biosynthesis of proteins. Like all other amino acids, it contains an amino group and a carboxylic acid. D-Aspartic Acid is a kind of alfa amino acid. It is widespread in the biosynthesis of role. D Aspartic Acid can be made from oxaloacetic acid by transamination. For plants and microorganisms D-aspartic acid is the raw material of several kinds of amino acids,like methionine, threonine, isoleucine and lysine.
