4490 Carbamoyl phosphate Carbamoyl phosphate is a precursor of both arginine and pyrimidine biosynthesis. It is a labile and potentially toxic intermediate. Carbamoyl phosphate is a molecule that is involved in ridding the body of excess nitrogen in the urea cycle, and also in the synthesis of pyrimidines. It is produced from carbon dioxide, ammonia, and phosphate (from ATP) by the enzyme carbamoyl phosphate synthase. 590-55-6 278 CH4NO5P White powder. No indication of carcinogenicity to humans (not listed by IARC). This is an endogenously produced metabolite found in the human body. It is used in metabolic reactions, catabolic reactions or waste generation. 2014-08-29T06:51:16Z 2026-04-06T11:03:53Z Carbamoyl phosphate C00169 17672 CARBAMOYL-P CP true NC(=O)OP(O)(O)=O CH4NO5P InChI=1S/CH4NO5P/c2-1(3)7-8(4,5)6/h(H2,2,3)(H2,4,5,6) FFQKYPRQEYGKAF-UHFFFAOYSA-N 141.0199 140.982708755 Endogenous Solid HMDB01096 CHEMBL369105 272 CHEM003396 DTXSID20171923 NS00121293 (carbamoyloxy)phosphonic acid
