D-Aspartic acid Usage And Synthesis
Chemical PropertiesWhite or almost white crystalline powder
UsesA 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.
DefinitionChEBI: The D-enantiomer of aspartic acid.
Biological ActivityEndogenous 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.
