L-ASPARTIC ACID UNLABELED is a naturally occurring proteinogenic amino acid in the aspartic acid class, featuring an α-amino group and an α-carboxyl group on the backbone and a side chain terminated by a carboxylic acid (-CH2-COOH). The molecule bears stereochemistry consistent with the L-form indicated by its name, and the side-chain carboxyl functionality provides an additional acidic group that can participate in hydrogen bonding and ionic interactions while remaining capable of forming zwitterionic species depending on pH. As an unlabelled free amino acid, it is used as a building block for peptide and amino acid derivative synthesis and as a reference material in analytical method development, including studies that require an authentic aspartate standard.
