Aspartic acid (abbreviatit as Asp or D; encodit bi the codons [GAU an GAC]), an aa kent as aspartate, is an α-amino acid that is uised in the biosynthesis o proteins. It conteens an α-amino group (which is in the protonated −NH+
form unner biological condeetions), an α-carboxylic acid group (which is in the deprotonatit −COO form unner biological condeetions), an a side chain CH2COOH. Unner pheesiological condeetions in proteins the sidechain uisually occurs as the negatively chairged aspartate form, −COO. It is semi-essential in humans, meanin the bouk can seenthesize it frae oxaloacetate.
