Molecule Details
Biochem/physiol Actions
Principal neurotransmitter for fast synaptic excitation.
L-Aspartic acid is a negatively charged carboxyl side-chain containing α amino acid. Aspartic acid is involved in nitrogen metabolism via its inter-conversion to oxaloacetate (OAA). As one of the 22 proteinogenic amino acids L-Asp is incorporated into proteins by translation processes in vitro. L-Aspartic acid is a non-essential amino acid added to cell culture media. L-aspartate supports polyamine biosynthesis.
