DL-Aspartic acid Chemical Properties,Usage,Production

Chemical Properties

White crystalline powder

Uses

Food additive.

Uses

DL-Aspartic acid is used in studies on factors and conditions that enhance semen and sperm quality. Its conjugate base D-aspartate has potential use as a therapeutic agent in the treatment of schizophrenia-related symptoms.

Definition

ChEBI: An alpha-amino acid that consists of succinic acid bearing a single alpha-amino substituent

Biological Functions

DL-Aspartic acid (DL-Asp) is a racemic mixture of the proteinogenic amino acid L-aspartate and the non-proteinogenic amino acid D-aspartate. DL-Aspartic acid is used in studies on factors and conditions that enhance semen and sperm quality.

Hazard

Very low toxicity.

Safety Profile

Very low toxicity byintraperitoneal route. When heated to decompositionemits toxic fumes of NOx.

Purification Methods

Likely impurities are glutamic acid, cystine and asparagine. Crystallise the acid from water by adding 4 volumes of EtOH and dry it at 110o. [Greenstein & Winitz The Chemistry of the Amino Acids J. Wiley, Vol 3 p 1856 1961, Beilstein 4 IV 2998, 3000.]
