WebThe urea cycle (also known as the ornithine cycle) is a cycle of biochemical reactions occurring in many animals that produces urea from ammonia (NH 3 ). This cycle was the first metabolic cycle discovered ( Krebs and Kurt Henseleit, 1932). In mammals, the urea cycle takes place only in the liver. WebThe urea cycle is a very important pathway which describes the mechanism by which the 'unwanted nitro- gen' of amino acids is eliminated from the body. The entire sequence of reactions, which occurs in the mam- malian liver, serves the vital function of disposal of ammonia, which is potentially toxic.

WebJun 9, 2024 · 1. Urea Cycle • Urea: End product of protein metabolism/amino acid metabolism. • The nitrogen of amino acids which is converted to ammonia is toxic to the body. Therefore it is converted to urea and detoxified. • Urea cycle is also known as Krebs-Henseleit cycle because the metabolic cycle was elucidated by Hans Krebs and Kurt … WebThe urea cycle or the ornithine cycle describes the conversion reactions of ammonia into urea. Since these reactions occur in the liver, the urea is then transported to the kidneys where it is excreted. The overall urea …
