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.
