Phosphoric acid | H3PO4

Phosphate is a salt of phosphoric acid. In organic chemistry, a phosphate, or organophosphate, is an ester of phosphoric acid.Organic phosphates are important in biochemistry, biogeochemistry and ecology. Phosphate (Pi) is an essential component of life. In biological systems, phosphorus is found as a free phosphate ion in solution and is called inorganic phosphate, to distinguish it from ...
