L-CITRULLINE (UREIDO-13C; 5,5-D2) is an isotopically labeled, non-essential amino acid characterized by a urea (ureido) side chain that distinguishes citrulline from proteinogenic amino acids with standard carbonyl-free side chains. The molecule bears an α-amino group and a carboxyl group, with the side-chain ureido carbon enriched in 13C and with deuterium incorporation at the 5,5 positions (5,5-D2), while retaining the L stereochemical designation indicated by the product name. In chemical biology and analytical workflows, this labeled citrulline is used as a substrate or tracer for isotopic studies, including mass spectrometry or NMR-based monitoring of citrulline-related transformations and incorporation into labeled amino acid and peptide derivatives.
