GLYCINE (13C2; 15N) is an isotopically labeled form of the simplest proteinogenic amino acid, containing a side chain that is a hydrogen and therefore features the standard amino acid backbone. The molecule bears an amino functional group and a carboxyl functional group, with the carbon atoms and the nitrogen atom labeled as 13C2 and 15N, respectively, while retaining the glycine connectivity and stereochemical neutrality associated with this achiral amino acid. This labeled amino acid is used in isotopic tracing, quantitative mass spectrometry and NMR method development, and the preparation of labeled peptide or protein fragments where incorporation of the 13C/15N signature supports structural and compositional analysis.
