L-METHIONINE (15N,) is an isotopically labeled, proteinogenic amino acid in which the amino nitrogen is enriched with 15N while the side chain retains the thioether functionality characteristic of methionine. The molecule contains a free α-amino group and a free α-carboxyl group, with a thioether-containing sulfide side chain that can participate in redox and nucleophilic interactions under appropriate conditions, and it is presented in the L stereochemical form as indicated by the product name. L-METHIONINE (15N,) is used as a labeled substrate for isotopic tracing, mass spectrometry-based analytical method development, and peptide or protein labeling workflows where incorporation of the 15N-labeled methionine enables tracking of nitrogen-containing fragments and quantitation in biochemical and chemical biology studies.
