Biochem/physiol Actions

Principal neurotransmitter for fast synaptic excitation.

L-Aspartic acid is associated with protein biosynthesis (proteinogenic) and neurotransmission

General description

Aspartic acid (Asp) is a non-essential amino acid. It makes up to 5% of the amino acids in a protein. The GAC and GAU codons encode Asp. This is a chiral molecule and occurs in two enantiomers namely L-Asp and D-Asp.
