Phosphatidylinositol diC16 (PI diC16) is a synthetic purified dipalmitoyl PI.Phosphoinositides (PIPns) are minor components of cellular membranes but are integral signaling molecules for cellular communication. Phosphatidylinositol (PI or PtdIns) is biosynthesized from CDP-diacylglycerol and inositol by phosphatidylinositol synthase. PI is the building block for phosphoinositide polyphosphates through phosphorylation by PI-kinases and is a substrate for PI-PLC yielding diacylgelycerol.Alternate Names: Dipalmitoyl Phosphatidylinositol PtdIns C16 or PI C16 (16:0/16:0) PIBulk discounts available please email echelon@echelon-inc.com for information.
