L-CYSTEINE (3,3-D2) is an isotopically labeled, naturally occurring sulfur-containing amino acid in which the side-chain thiol is attached to a deuterated methylene unit (D2 at the 3,3-positions). The molecule contains a free amino group and a free carboxyl group as well as a thiol functional group that can participate in redox and nucleophilic chemistry, with the isotopic substitution indicated by the (3,3-D2) label while the stereochemical form is specified as L. L-CYSTEINE (3,3-D2) is used in isotopic tracing and analytical method development to monitor cysteine-related transformations, quantify incorporation into peptide or protein materials, and support mass spectrometry or NMR-based studies where deuterium labeling improves detectability or enables kinetic and distribution measurements.
