L-GLUTAMIC ACID (13C5,D5,15N) is an isotopically labeled form of the proteinogenic amino acid glutamic acid, featuring the standard α-amino and α-carboxyl functional groups attached to a side chain containing an additional carboxylate (γ-carboxyl) that is characteristic of the acidic amino acid class. The molecule bears five 13C atoms, five deuterium atoms, and one 15N atom within the glutamate framework, enabling isotopic tracking while retaining the native glutamate connectivity and stereochemical identity implied by the L-designation. As a labeled free amino acid, it is used in isotopic tracing, NMR and mass spectrometric method development, and quantitative studies of amino acid incorporation or turnover in chemical biology and protein/peptide-related analytical workflows.
