Urea cycle — The urea cycle (also known as the ornithine cycle) is a cycle of biochemical reactions occurring in many animals that produces urea ((NH2)2CO) from ammonia (NH3). This cycle was the first metabolic cycle discovered (Hans Krebs and Kurt Henseleit … Wikipedia

Urea cycle. Diagrammatic representation of reactions by which excess nitrogen in the form of ammonia is converted to soluble urea, using L-ornithine as a recyclable carrier. Enzymes involved are denoted by circled numerals: (1), carbamoyl-phosphate synthase (ammonia); (2), ornithine carbamoyltransferase; (3), argininosuccinate synthase; (4), argininosuccinate lyase; (5), arginase.
