It is a carbocyclic polyol, a constituent of phospholipids (phosphatidyl inositols) involved in membrane structure and as part of the signaling mechanism for hormones which act at the cell surface. A number of biological processes are involved, including insulin signal transduction, cytoskeleton assembly, nerve guidance, intracellular calcium concentration control, cell membrane potential maintenance, serotonin activity modulation, breakdown of fat and reducing blood cholesterol.
