L-LEUCINE (1-13C) is an isotopically labeled form of the proteinogenic amino acid leucine, featuring a branched aliphatic side chain and the typical amino acid backbone with an amino group and a carboxyl group. The molecule bears the 13C label at carbon position 1 on the amino acid skeleton while maintaining the L stereochemical configuration indicated by the name. In biochemical and analytical workflows, the labeled leucine functions as an isotopic tracer for amino acid incorporation studies, metabolic flux or turnover measurements, and LC-MS or NMR method development that distinguishes labeled from unlabeled leucine during peptide or protein-related analyses.
