Phosphate group
Inositol phosphates are a group of mono- to polyphosphorylated inositols. They play crucial roles in diverse cellular functions, such as cell growth, apoptosis, cell migration, endocytosis, and cell differentiation. The group comprises:
- inositol monophosphate (IP)
- inositol bisphosphate (IP2)
- inositol trisphosphate (IP3)
- inositol pentakisphosphate (IP5)
- inositol hexaphosphate (IP6) also known as phytic acid, or phytate (as a salt).
Functions

Inositol trisphosphates act on the inositol triphosphate receptor to release calcium into the cytoplasm. Further reading: Function of calcium in humans
Other
Inositol tetra-, penta-, and hexa-phosphates have been implicated in gene expression[1] and Steger[2] (both in Science Magazine).
