Theurea cycle(also known as theOrnithine cycle) is a cycle ofbiochemicalreactions occurring in many animals that producesurea((NH2)2CO) fromammonia(NH3). This cycle was the first metabolic cycle discovered, five years before the discovery of theTCA cycle. Inmammals, the urea cycle takes place primarily in theliver, and to a lesser extent in thekidney.

The entire process of this cycle converts two amino groups, one from NH4+ and one from Asp, and a carbon atom from HCO3, to the relatively nontoxic excretion product urea at the cost of four "high-energy" phosphate bonds. To enter the cycle, ammonia is converted to carbomyl phosphate.
