Product Introduction

L‑Aspartic Acid is the L‑enantiomer of aspartic acid, a proteinogenic α‑amino acid and a component of the aspartate family. It acts as an endogenous metabolite in prokaryotic and eukaryotic systems and functions as an excitatory neurotransmitter in the central nervous system. Biochemically, L‑aspartic acid serves as a precursor for oxaloacetate in the tricarboxylic acid cycle, supports nitrogen shuttling and urea cycle activity, and contributes to cellular energy homeostasis. It is a non‑essential amino acid biosynthesized in vivo via transamination from oxaloacetate and does not rely on exogenous dietary intake under normal physiological conditions. The conjugate base L‑aspartate mediates ion transport and osmotic balance across biological membranes.
