      an amino acid (q.v.) obtainable as a product of the hydrolysis of proteins. First isolated in 1868 from legumin in plant seeds, aspartic acid is one of several so-called nonessential amino acids for mammals; i.e., they can synthesize it from oxaloacetic acid (formed in the metabolism of carbohydrates) and do not require dietary sources.
