L-ALANINE (1-13C; 15N) is an isotopically labeled form of the proteinogenic amino acid L-alanine, featuring a methyl side chain and the standard amino acid backbone with an amino group and a carboxyl group. The molecule contains a 13C label at the carbon position specified by the "1-13C" designation and a 15N label on the nitrogen of the amino group, preserving the native functional-group connectivity and the L stereochemical form indicated by the product name. As a free amino acid, it is used as an isotopic tracer and analytical standard in labeling, amino acid metabolism studies, and mass spectrometry or NMR method development where incorporation of the labeled carbon and nitrogen into downstream analytes is monitored.
CAT No: L-Iso-0008
