The urea cycle (also known as the ornithine cycle) is a cycle of biochemical reactions that produces urea (NH2)2CO from ammonia (NH3). Animals that use this cycle, mainly amphibians and mammals, are called ureotelic. The urea cycle converts highly toxic ammonia to urea for excretion. This cycle was the first metabolic cycle to be discovered (Hans Krebs and Kurt Henseleit, 1932), five years before the dis… SpletMammals, for whom water balance and weight are not generally a problem, excrete most of their nitrogenous waste as urea, which is water-soluble; such animals are termed ureotelic. In this program you will investigate the synthesis of urea by isolated liver cells - you will be repeating the experiments that Krebs and Henseleit carried out when ...

Two nonprotein amino acids (ornithine and citrulline) are involved in the urea cycle.
