Urea cycle. The ornithine cycle (also known as the 'urea cycle') is a cycle of biochemical reactions occurring in many animals that produce urea ((NH2)2CO) from ammonia (NH3). This cycle was the first metabolic cycle discovered (Hans Krebs and Kurt Henseleit, 1932), five years before the discovery of the TCA cycle.
