WebThe conversion of ammonia into urea through a series of biochemical reactions is known as the urea cycle or ornithine cycle. It takes place in the liver with the help of mitochondrial and cytosolic enzymes. It is an important pathway in amphibians and mammals as they help in disposing highly toxic ammonia by converting it into urea.

WebThe urea cycle, probably the most well-known metabolic pathway, involves arginine as a carrier of nitrogenous waste. The final step in that pathway is catalyzed by the enzyme arginase (ARG), converting arginine to ornithine and urea; this allows urea to be available for excretion and regenerates ornithine to reenter the cycle. WebL -Ornithine is one of the products of the action of the enzyme arginase on L - arginine, creating urea. Therefore, ornithine is a central part of the urea cycle, which allows for the disposal of excess nitrogen. Ornithine is recycled and, in a manner, is a catalyst. First, ammonia is converted into carbamoyl phosphate ( H. 3 ).
