What is L-Aspartic acid?

L-aspartic acid is the L-enantiomer of aspartic acid. It has a role as a neurotransmitter, a mouse metabolite and an Escherichia coli metabolite. It is a L-alpha-amino acid, an aspartate family amino acid, an aspartic acid and a proteinogenic amino acid. It is a conjugate acid of a L-aspartate(1-). It is an enantiomer of a D-aspartic acid.
