| 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.] |
