L-CYSTEINE (2,3,3-D3) is an isotopically labeled, naturally occurring sulfur-containing amino acid in which the side chain bears a thiol group and the molecule retains the standard amino acid backbone with an amino functional group and a carboxyl functional group. The (2,3,3-D3) designation indicates deuterium incorporation at the specified carbon positions of the cysteine skeleton, preserving the amino acid's overall connectivity and thiol-bearing side-chain functionality while shifting its isotopic composition for labeling and tracing. This labeled amino acid is used in isotopic tracing, mass spectrometry-based analytical method development, and quantitative studies of cysteine-containing peptides and proteins where distinguishing labeled from unlabeled material is required.
