| DL-Aspartic acid Usage And Synthesis |
| 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. | | 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. | | 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.] |
