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