DETAILS

Description (English)

Biochem/physiol Actions
Principal neurotransmitter for fast synaptic excitation.
L-Aspartic acid is a natural proteinogenic amino acid that may be used in the formulation of cell culture media and in protein and polypeptide synthesis systems and procedures. L-Aspartic acid, an NMDA receptor agonist and non-specific glutamate receptor agonist, is used to differentiate and study the mechanisms of NMDA receptors.
