L-METHIONINE (METHYL-D3) is an isotopically labeled, proteinogenic amino acid featuring a thioether-containing methionine side chain and an α-amino acid backbone with a free amino group and a free carboxyl group. The molecule bears three deuterium atoms specifically on the methyl substituent of the thioether (methyl-D3), retaining the stereochemical identity indicated by the L prefix while presenting the characteristic sulfur-containing side chain functionality. It is used as an isotopic tracer and analytical reference in amino acid metabolism studies, peptide or protein labeling workflows, and mass spectrometry-based quantification where the deuterium label enables differentiation from unlabeled methionine.
CAT No: L-Iso-0444
