L-METHIONINE (1,2,3,4-13C4; 15N) is an isotopically labeled proteinogenic amino acid of the thioether-containing family, featuring the standard amino acid backbone with a side chain that bears a thioether (methylthio) group. The molecule contains an amino functional group and a carboxyl functional group, and the carbon atoms at positions 1-4 and the nitrogen atom are enriched with 13C and 15N, respectively, without altering the underlying connectivity or the methionine side-chain functionality. As a stable isotope tracer, it is used in isotopic labeling workflows for amino acid metabolism studies, peptide and protein labeling experiments, and analytical method development where mass-dependent detection of labeled fragments is required.
