What is Ammonia?
Ammonia is an azane that consists of a single nitrogen atom covelently bonded to three hydrogen atoms. It has a role as a NMR chemical shift reference compound, a metabolite, a neurotoxin, a nucleophilic reagent, a mouse metabolite, an EC 3.5.1.4 (amidase) inhibitor and a refrigerant. It is a gas molecular entity, an azane and a mononuclear parent hydride. It is a conjugate base of an ammonium. It is a conjugate acid of an azanide.
