Properties

Aspartic acid is a non-essential amino acid. It is a colorless, crystalline substance that dissolves weakly in water and does not dissolve in alcohol.

Occurrence and production

Aspartic acid is the building block of many types of proteins: it is found in zein, that is, maize protein; in casein, the protein in cow’s milk; and in wool keratine. Biosynthesis of aspartic acid proceeds from oxaloacetic acid.

Uses

Aspartic acid is a neurotransmitter in the central nervous system of vertebrates. It is also used in the treatment of leukemia.
