Description: 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[vague]), 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. 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. Allantoin is a major metabolic intermediate in many other organisms
including plants and bacteria.
