Allantoin is a chemical compound with formula c4h6n4o3. it is also called 5-ureidohydantoin or glyoxyldiureide. it is a diureide of glyoxylic acid. named after the allantois, an amniote embryonic excretory organ in which it concentrates during development in most mammals except humans and higher apes, it is a product of oxidation of uric acid by purine catabolism. after birth, it is the predominant means by which nitrogenous waste is excreted in the urine of these animals.[2] in humans and higher apes, the metabolic pathway for conversion of uric acid to allantoin is not present, so the former is excreted. recombinant rasburicase is sometimes used as a drug to catalyze this metabolic conversion in patients. in fish, allantoin is broken down further (into ammonia) before excretion.[3] allantoin is a major metabolic intermediate in many other organisms including plants and bacteria
