L-PHENYLALANINE (13C9; 15N) is an isotopically labeled, naturally occurring amino acid featuring a benzyl side chain attached to the alpha carbon, with the amino acid backbone bearing both an amino group and a carboxyl group. The molecule is labeled with nine 13C atoms and one 15N atom, enabling isotopic tracking while retaining the stereochemical identity implied by the L designation and the characteristic aromatic functionality of phenylalanine. As an isotopically enriched substrate for biochemical and analytical studies, it is used in metabolic tracing, protein and peptide composition analysis, and mass spectrometry-based quantitation where the isotopic signature supports discrimination from unlabeled phenylalanine.
