L-GLUTAMIC ACID (13C5; 15N) is an isotopically labeled, proteinogenic amino acid belonging to the acidic amino acid class, featuring a side chain with a carboxylic acid functionality attached to the α-amino acid backbone. The molecule bears an α-amino group and an α-carboxyl group, and the glutamate side-chain carboxyl group provides a second acidic functionality that can participate in acid-base equilibria and coordination chemistry, while the (13C5; 15N) labeling indicates incorporation of five 13C atoms and one 15N atom within the glutamate framework. It is used in isotopic tracing, mass spectrometric or NMR-based analytical method development, and quantitative studies that require glutamate-specific labeling in peptide and protein analysis workflows.
CAT No: L-Iso-0214
