Phosphatidylinositol-(5)-P1 (1,2-dioctanoyl) (PtdIns-(5)-P1 (1,2-dioctanoyl)) is a synthetic analog of natural PtdIns featuring C8:0 fatty acids at the sn-1 and sn-2 positions. The compound features the same inositol and diacylglycerol (DAG) stereochemistry as the natural compound. PtdIns-(5)-P1 can be phosphorylated to di- (PtdIns-P2; PIP2) and triphosphates (PtdIns-P3; PIP3) by phosphoinositol (PI)-specific kinases. Hydrolysis of PtdIns-(4,5)-P2 by PI-specific phospholipase C generates inositol triphosphate (IP3) and DAG which are key second messengers in an intricate biochemical signal transduction cascade.WARNING This product is not for human or veterinary use.
