L-LEUCINE (15N) is an isotopically labeled, proteinogenic amino acid belonging to the aliphatic hydrophobic class, featuring a branched isobutyl side chain attached to the α-carbon. The molecule contains an amino group and a carboxyl group, with the amino nitrogen labeled as 15N while maintaining the standard leucine carbon framework and stereochemistry associated with L-leucine. As an isotopic tracer and analytical reference, L-LEUCINE (15N) is used in studies requiring nitrogen-specific labeling, including mass spectrometry-based quantification, isotopic labeling experiments in peptide and protein analysis, and the preparation of labeled amino acid building blocks for downstream synthetic or bioconjugation workflows.
CAT No: L-Iso-0353
