PIP2(16:0/22:3(10Z,13Z,16Z)) is a phosphatidylinositol bisphosphate. Phosphatidylinositol bisphosphates are acidic (anionic) phospholipids that consist of a phosphatidic acid backbone, linked via the phosphate group to a bisphosphorylated inositol (hexahydroxycyclohexane). Phosphatidylinositol bisphosphates are generated from phosphatidylinositols which are phosphorylated by a number of different kinases that place the phosphate moiety on positions 4 and 5 of the inositol ring, although position 3 can also be phosphorylated. Phosphatidylinositols bisphosphates can have many different combinations of fatty acids of varying lengths and saturation attached at the C-1 and C-2 positions. Fatty acids containing 18 and 20 carbons are the most common. PIP2(16:0/22:3(10Z,13Z,16Z)), in particular, consists of one chain of palmitic acid at the C-1 position and one chain of (10Z,13Z,16Z-docosatrienoyl) at the C-2 position. The palmitic acid moiety is derived from fish oils, milk fats, vegetable oils and animal fats, while the (10Z,13Z,16Z-docosatrienoyl) moiety is derived from fish oils.
