| phosphatidylinositol | <biochemistry> A phosphatidic acid combined with inositol found in biomembranes and a precursor to certain cellular signals. Sometimes referred to as inositide. It is a very important minor phospholipid in eukaryotes, involved in signal transduction processes. Contains myo inositol linked through the 1 hydroxyl group to phosphatidic acid. The 4 phosphate (PIP) and 4, 5 bisphosphate derivatives PIP2) are formed and broken down in membranes by the action of specific kinases and phosphatases (futile cycles). Signal sensitive phospholipase C enzymes remove the inositol moiety, in particular from 1,4,5 trisphosphate (PIP2) as inositol 1,4,5 triphosphate (Ins P3: IP3). Both the diacyl glycerol and products act as second messengers. Synonym: phosphoinositide. (20 Sep 2002) |

| phosphatidylinositol |
a phospholipid in which the sugar inositol is attached to the phosphate group of phosphatidic acid by an ester linkage and the fatty acyl groups are usually arachidonate and stearate; additional phosphates can be attached to the sugar. It is a minor constituent of cell membranes found primarily in the plasma membrane. It is converted by specific kinases to mono- and diphosphorylated forms, phosphoinositides involved in hormonally activated calcium mobilization.
