L-PROLINE (1-13C) is an isotopically labeled, proteinogenic amino acid belonging to the cyclic imino acid family, featuring a five-membered pyrrolidine ring that forms the side chain and links back to the α-amino and α-carboxyl groups. The molecule bears an α-amino group and a carboxylic acid functionality, with the ring nitrogen as the characteristic secondary amine; the "(1-13C)" label indicates incorporation of 13C at the carbon-1 position within the proline framework. As a stable-isotope tracer, L-PROLINE (1-13C) is used in peptide and protein labeling workflows, amino acid metabolism and turnover studies, and analytical method development where isotopic incorporation or mass-based detection of proline-derived species is required.
