Phosphoryl group derives from phosphoric acid and has an overall negative charge. Its chemical formula is PO32-. Phosphoryl group consists of a phosphorus atom in the centre and three oxygen atoms attached to it[1]. It has a sp3 hybridisation. It is often mistaken with phosphate group, which differs, as it consists four oxygen atoms linked to phosphorous.
Phosphoryl group takes part in biologically important reaction called phosphoryl transfer. The group it transferred from a phosphate ester to a nucleophile. Phosphates (such as adenosine triphosphate - ATP) are also involved in the process[2].
