Phosphate group: A functional group characterized by a phosphorus atom bonded to four oxygen atoms (three single bonds and one double bond). One of these oxygen atoms must be bonded to another atom; if not, the structure is a phosphate ion. Generic phosphate group molecular structure.
A phosphate (PO 4 3â) is an inorganic chemical and a salt of phosphoric acid.queous phosphate exists in four forms. In strongly basic conditions, the phosphate ion (PO 4 3â) predominates, whereas in weakly basic conditions, the hydrogen phosphate ion (HPO 4 2â) is prevalent. In weakly acid conditions, the dihydrogen phosphate ion (H 2 PO 4 â) is most common.
