It is produced naturally in the human body and in nature—in water, soil and air, even in tiny bacteria molecules. Because ammonia evaporates quickly, it is commonly used in glass cleaning solutions to help avoid streaking. 2H2O exist and have been shown to consist of ammonia and water molecules linked by intermolecular hydrogen bonds. Ammonia also is renewed naturally as part of the nitrogen cycle that already occurs as plants fertilize. No health effects have been found in humans exposed to typical amounts of ammonia that exist in the environment. A form of liquid ammonia made from fermented urine was used for dyeing clothing in the Middle Ages.

Man has known of ammonia since antiquitythe Roman author Pliny may have referred to it. In human health, ammonia and the ammonium ion are vital components of metabolic processes. The human body makes ammonia when the body breaks down foods containing protein into amino acids and ammonia, then converting the ammonia into urea. Ammonia is also produced in the human body and is commonly found in nature. Ammonia, also known as NH3, is a colorless gas with a distinct odor composed of nitrogen and hydrogen atoms. Normally, ammonia is processed in the liver, where it is changed into another waste product called urea. It has a high heat of vaporization (23.3 kilojoules per mole at its boiling point) and can be handled as a liquid in thermally insulated containers in the laboratory. Ammonia tests measure the level in the blood. If your body can't process or eliminate ammonia, it builds up in the bloodstream. If you have elevated ammonia levels, it is typically due to a problem with your liver function. Hydrazine, N2H4, is a molecule in which one hydrogen atom in NH3 is replaced by an ―NH2 group.
