Ammonia (NH3) or the ammonium ion (NH4 +) is found in the atmosphere, rainwater, soil, seawater, and volcanic areas. It is widely used as fertilizer, being an important source of nitrogen for living systems. It also plays a role in animal physiology. Ammonia is produced by amino acid metabolism and is converted to urea in the human liver through the urea cycle. Ammonia acts as a precursor for various other nitrogen compounds. It is a colorless gas with pungent odor and can be easily liquefied. It is also used as a feed supplement in livestock industry.
