L-ALANINE (3-13C; 3,3,3-D3) is an isotopically labeled, naturally occurring amino acid in the alanine class, featuring a primary amino group and a carboxyl group attached to a methyl-bearing side chain. The molecule bears a 13C label at the carbon corresponding to the side-chain methyl carbon and three deuterium atoms at the same methyl position (3,3,3-D3), retaining the amino acid backbone stereochemistry associated with the L form. As an isotopically enriched free amino acid, it is used in isotopic tracing, NMR and MS-based analytical method development, and quantitative studies where incorporation or detection of alanine-derived fragments is required for chemical biology, protein/peptide composition analysis, or metabolic labeling experiments.
