Webphosphate: [noun] a salt or ester of a phosphoric acid. the trivalent anion PO43− derived from phosphoric acid H3PO4. an organic compound of phosphoric acid in which the acid group is bound to nitrogen or a carboxyl group in a way that permits useful energy to be released (as in metabolism). In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid, aka. phosphoric acid H3PO4. The phosphate or orthophosphate ion [PO 4] is derived from phosphoric acid by the removal of three protons H . Removal of one or two protons gives the dihydr…
