L-LEUCINE (1-13C; 15N+) is an isotopically labeled, naturally occurring amino acid belonging to the aliphatic, hydrophobic leucine family, featuring an isobutyl side chain attached to the α-carbon. The molecule contains an α-amino group and a carboxyl group, with the side chain and backbone bearing 13C at the specified position and 15N at the specified nitrogen site, enabling differentiation by mass spectrometric or NMR-based analytical methods while maintaining the same connectivity as the unlabeled amino acid. L-LEUCINE (1-13C; 15N+) is used as an isotopic tracer or reference material in labeling, quantification, and structural studies of amino acid incorporation into peptides and proteins, as well as in analytical method development for amino acid profiling.
CAT No: L-Iso-0345
