Metabolite Identification
Common NameHydroxide
DescriptionHydroxide, also known as hydroxy or hydroxide ion, belongs to the class of inorganic compounds known as non-metal hydroxides. These are inorganic non-metallic compounds containing the hydroxide group as its largest oxoanion. Hydroxide is an extremely weak basic (essentially neutral) compound (based on its pKa). Hydroxide exists in all living species, ranging from bacteria to humans.
