| | D-Aspartic acid Usage And Synthesis |
| Chemical Properties | White or almost white crystalline powder | | Uses | A non-essential amino acid found in food sources and dietary supplements. D-Aspartic acid's conjugate base D-aspartate has potential use as a a therapeutic agent in the treatment of schizophrenia-related symptoms. | | Uses | D-Aspartic acid modulates melatonin synthesis in the pineal gland. | | Definition | ChEBI: The D-enantiomer of aspartic acid. | | Application | Dietary inclusion of barley sprout, D-Aspartic acid, or their combination have a potential to improve various aspects of reproductive performance in aging roosters[2]. | | reaction suitability | reaction type: solution phase peptide synthesis | | Biological Activity | Endogenous NMDA receptor agonist with similar activity to the L-isomer (L-Aminosuccinic acid ). Also a non-metabolizable substrate for EAA uptake systems. Modulates melatonin synthesis in the pineal gland. | | Synthesis | In a reaction vessel, 4.85 g (0.03 mol) of dimethyl (S)-2-aminosuccinate was added to 50 mL of 6 M potassium hydroxide solution and the hydrolysis reaction was carried out by heating and refluxing for 3 hrs. Upon completion of the reaction, the pH of the reaction solution was adjusted to 6.5 with 6 N hydrochloric acid.The reaction solution was purified by passing it through a regenerated cation exchange resin column and the effluent with pH=4 was collected. The collected effluent was concentrated under reduced pressure to one-fifth of the original volume and then precipitated by adding 95% methanol. The precipitate was collected by filtration and dried to give 3.3 g of D-aspartic acid in 82.5% yield. | | storage | Room temperature | | References |
