<span style="font-family:Arial;font-size:12px;">Aspartic
acid (abbreviatedas D-AA, Asp, or D) is an α-amino acid with the
chemical formulaHOOCCH(NH2)CH2COOH. The carboxylate anion and salts of
aspartic acid are knownas aspartate. The L-isomer of aspartate is one of
the 22 proteinogenic aminoacids, i.e., the building blocks of proteins.
Its codons are GAU and GAC.</span><br />
<span style="font-family:Calibri,zapf dingbats;font-size:14px;"><span style="font-family:Arial;font-size:12px;">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 inbiosynthesis. As with all amino acids, the
presence of acid protons depends onthe residue's local chemical
environment and the pH of the solution. </span><br />
