WebOrnithine cycle. Biochemistry of reactions The cycle of urea synthesis takes place in several stages. The general scheme of the ornithine cycle is presented below (picture), so we will analyze each reaction separately. The first two stages proceed directly in the mitochondria of the liver cells. 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 ).
