L-GLUTAMINE (1,2-13C2) is an isotopically labeled amino acid derivative of L-glutamine in which the carbon atoms at positions 1 and 2 are enriched with 13C, retaining the glutamine backbone with a side chain that terminates in a primary amide. The molecule contains a free α-amino group and a free α-carboxyl group alongside the side-chain amide functionality, and the stereochemistry is specified as L by the product name. Labeled glutamine is used as a substrate or tracer in isotopic labeling and mass spectrometry-based analytical workflows, supporting studies that track carbon incorporation and distribution during amino acid transformation, peptide/protein synthesis experiments, and structure-spectral correlation for glutamine-containing systems.
CAT No: L-Iso-0241
