L-CYSTEINE (13C3) is an isotopically labeled, free amino acid belonging to the cysteine family, featuring a thiol-bearing side chain attached to the α-carbon of the amino acid backbone. The molecule contains an amino group and a carboxyl group, with the side-chain thiol providing a sulfur functional handle that can participate in redox and thiol-disulfide chemistry, while three carbon atoms in the structure are enriched with 13C as indicated by the product name. L-CYSTEINE (13C3) is employed for isotopic tracing and quantitative analytical method development in contexts such as amino acid profiling, metabolic or protein-related labeling studies, and mass spectrometry-based detection where the 13C label enables discrimination from unlabeled cysteine.
