Identification
Name:Citrulline
DescriptionCitrulline is an amino acid made from ornithine and carbamoyl phosphate in one of the central reactions in the urea cycle. It is also produced from arginine as a by-product of the reaction catalyzed by NOS family (NOS; EC 1.14.13.39). In this reaction arginine is first oxidized into N-hydroxyl-arginine, which is then further oxidized to citrulline concomitant with the release of nitric oxide.; EC 1.14.13.39). Citrulline's name is derived from citrullus, the Latin word for watermelon, from which it was first isolated.
