L-CITRULLINE (UREIDO-15N1) contains the amino acid framework of citrulline, featuring a ureido side chain attached to the carbon backbone and a free α-amino group and α-carboxyl group. The side chain ureido functionality bears one 15N label at the ureido nitrogen position indicated by "UREIDO-15N1," while the remaining atoms correspond to the native citrulline connectivity; the molecule is provided as the L stereochemical form as written in the product name. This isotopically labeled amino acid is used in isotopic tracing, quantitative LC-MS or NMR analytical method development, and structure-activity or metabolic-incorporation studies where incorporation or transformation of the ureido nitrogen can be monitored.
