Biochem/physiol Actions

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.
Principal neurotransmitter for fast synaptic excitation.

Glutamate transporters play important roles in the termination of excitatory neurotransmission and in providing cells throughout the body with glutamate for metabolic purposes. The high-affinity glutamate transporters EAAC1 (SLC1A1), GLT1 (SLC1A2), GLAST (SLC1A3), EAAT4 (SLC1A6), and EAAT5 (SLC1A7) mediate the
