| Common Name | (2r)-3-(hexadecanoyloxy)-2-[(5z,8z,11z,14z)-icosa-5,8,11,14-tetraenoyloxy]propoxy([(1s,2r,3r,4s,5s,6r)-2,3,4,5,6-pentahydroxycyclohexyl]oxy)phosphinic acid |

| Description | PI(16:0/20:4(5Z,8Z,11Z,14Z)), also known as phosphatidylinositol(16:0/20:4) Or pi(16:0/20:4), Belongs to the class of organic compounds known as 1-phosphatidyl-1d-myo-inositols. These are lipids containing a myo-inositol attached to the phosphate group of a glycerol-3-phosphate moiety, and two acyl chains linked to the glycerol at the O1- and O2- positions, through ester linkages. Phosphatidylinositols are important lipids, both as a key membrane constituent and as a participant in essential metabolic processes, both directly and via a number of metabolites. Seven different isomers are known, but the most important in both quantitative and biological terms are phosphatidylinositol 4-phosphate and phosphatidylinositol 4,5-bisphosphate. Phosphatidylinositol can be 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 by a specific kinase. Fatty acids containing 18 and 20 carbons are the most common. In most organisms, the stereochemical form of this inositol is myo-D-inositol (with one axial hydroxyl in position 2 with the remainder equatorial), although other forms can be found in certain plant phosphatidylinositols. PI(16:0/20:4(5Z,8Z,11Z,14Z)) is an extremely weak basic (essentially neutral) compound (based on its pKa). Phosphatidylinositols are acidic (anionic) phospholipids that consist of a phosphatidic acid backbone, linked via the phosphate group to inositol (hexahydroxycyclohexane). PIs composed exclusively of non-phosphorylated inositol exhibit a net charge of -1 at physiological pH. (2r)-3-(hexadecanoyloxy)-2-[(5z,8z,11z,14z)-icosa-5,8,11,14-tetraenoyloxy]propoxy([(1s,2r,3r,4s,5s,6r)-2,3,4,5,6-pentahydroxycyclohexyl]oxy)phosphinic acid is found in Trypanosoma brucei. Molecules with phosphorylated inositol (such as PIP, PIP2, PIP3, etc.) Are termed polyphosphoinositides. |
