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.
