The mobile metabolism generates many by-merchandise that are rich in nitrogen and should be cleared from the bloodstream, such as urea, uric acid, and creatinine. These by-products are expelled from the physique during urination, which is the primary technique for excreting water-soluble chemical compounds urea Iran from the physique. Urea serves an important function within the metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals. It is a colorless, odorless solid, extremely soluble in water, and virtually non-poisonous (LD50 is 15 g/kg for rats).

Originally, because it was not economic to recompress the ammonia and carbon dioxide for recycle, the ammonia a minimum of can be used for the manufacture of different products, for example ammonium nitrate or sulfate. (The carbon dioxide was often wasted.) Later process schemes made recycling unused ammonia and carbon dioxide practical.
