L-GLUTAMIC ACID (3,4-13C2) is an isotopically labeled L-glutamic acid in which two carbon atoms at positions 3 and 4 of the side chain are enriched with 13C, while the molecule retains the characteristic amino acid backbone with a primary α-amino group and a carboxylic acid. The side chain bears a second carboxyl group (γ-carboxyl), providing two carboxyl functionalities that can exist in different protonation states and participate in acid-base equilibria and metal coordination in solution, with the stereochemistry corresponding to the L form indicated by the product name. This labeled amino acid is used as a tracer and analytical standard in isotopic labeling studies, including NMR and mass spectrometry method development and quantitative analysis of glutamate-containing intermediates or peptide/protein components where glutamate incorporation or derivatization is monitored by the 13C signal.
