L-ASPARTIC ACID (13C4) is an isotopically labeled, naturally occurring amino acid derivative in which four carbon atoms of the aspartic acid skeleton are enriched with 13C, retaining the standard α-amino acid framework. The molecule contains a free α-amino group and a free α-carboxyl group alongside a side-chain carboxylic acid, providing two carboxyl functionalities that can participate in acid-base equilibria and coordinate metal ions depending on pH. L-ASPARTIC ACID (13C4) is used as a stable-isotope tracer and analytical reference for carbon-specific studies in amino acid metabolism research, protein and peptide composition analysis by mass spectrometry, and structure-labeling workflows where the labeled carbon distribution is tracked.
CAT No: L-Iso-0121
