L-LEUCINE (13C6;15N) is an isotopically labeled form of the proteinogenic amino acid L-leucine, featuring a branched aliphatic side chain characteristic of the leucine class. The molecule contains an amino group and a carboxyl group on the alpha-carbon, while the side chain bears six 13C atoms and the amino nitrogen is labeled with 15N, providing an isotopic signature useful for mass spectrometric and NMR-based analyses. As a labeled free amino acid, it is employed in isotopic tracing, quantitative metabolite or amino acid profiling, and peptide or protein labeling workflows where incorporation of a leucine residue or monitoring of leucine-containing species is required.
CAT No: L-Iso-0352
