Phosphate group

Inositol phosphates are a group of mono- to polyphosphorylated inositols. They have important messaging functions in the cells.

The group comprises:


Inositol triphosphate

Inositol trisphosphate act on the inositol triphosphate receptor to release calcium into the cytoplasm. Further reading: Function of calcium in humans


Inositol tetra-, penta-, and hexa-phosphates have been implicated in gene expression[1] and Steger[2] (both in Science Magazine).
