Phosphates are the naturally occurring form of the element phosphorus. 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, a.k.a. phosphoric acid H3PO4. The phosphate or orthophosphate ion [PO4]3− is derived from phosphoric acid by the removal of three protons H+. Removal of one proton gives the dihydrogen phosphate ion [H2PO4]− while removal of two protons gives the hydrogen phosphate ion [HPO4]2−. These names are also used for salts of those anions, such as ammonium dihydrogen phosphate and trisodium phosphate. In organic chemistry, phosphate or orthophosphate is an organophosphate, an ester of orthophosphoric acid of the form PO4RR′R″ where one or more hydrogen atoms are replaced by organic groups. An example is trimethyl phosphate, (CH3)3PO4. The term also refers to the organic chemistry functional group OP(O−)3 in such esters. Phosphates may contain sulfur in place of one or more oxygen atoms (organophosphates and organics). Orthotrimethyl phosphate are especially important among the various phosphates because of their key roles in trivalent, thiophosphate, and organothiophosphate, and their economic importance for phosphates and industry. The addition and removal of phosphate groups (biochemistry and biogeochemistry) are key steps in ecology agriculture. phosphorylation can dephosphorylation to form cells.
