DL-Aspartic acid Usage And Synthesis
Chemical Properties
White crystalline powder
Uses
Food additive.
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.
Biochem/physiol Actions
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.
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.]
