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) PI
