L-LEUCINE (1,2-13C2) is an isotopically labeled, proteinogenic amino acid belonging to the aliphatic side-chain class, featuring a branched isobutyl group attached to the α-carbon. The molecule contains an α-amino group and a carboxyl group and bears two 13C labels at the 1 and 2 positions of the carbon skeleton, with stereochemistry corresponding to the L-form indicated by the name. As a stable-isotope tracer, it is used in isotopic labeling and analytical method development to monitor incorporation, distribution, or transformation of leucine-containing structures in peptide and protein-related studies.
CAT No: L-Iso-0340
