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.

Application

L-Aspartic acid has been used:
  • as a metabolite to study the enzyme–metabolite interactions in the central metabolism of Escherichia coli by nuclear magnetic resonance (NMR)
  • in transmission electron microscopy
  • as a component of complete media for culturing Yeast strain

Biochem/physiol Actions

L-Aspartic acid is associated with protein biosynthesis (proteinogenic) and neurotransmission
Principal neurotransmitter for fast synaptic excitation.
