Phosphoryl Group vs. Phosphate Group: What's the Difference?

Edited by Sara Rehman || By Sumera Saeed || Published on December 30, 2023
A phosphoryl group is a trivalent group derived from phosphoric acid, while a phosphate group is a tetra-valent ion of phosphorus, oxygen, and hydrogen.

Key Differences

The phosphoryl group, represented as PO_3, is a functional group derived from phosphoric acid by the loss of one or two hydroxyl groups. In contrast, the phosphate group is a broader term often used to describe phosphoric acid derivatives, typically the PO_4^3- ion.
