PIP(22:3(10Z,13Z,16Z)/16:2(9Z,12Z))
IUPAC 名称
{[(1R,3S)-3-({[(2R)-3-(docosa-10,13,16-trienoyloxy)-2-(hexadeca-9,12-dienoyloxy)propoxy](hydroxy)phosphoryl}oxy)-2,4,5,6-tetrahydroxycyclohexyl]oxy}phosphonic acid
描述
PIP(22:3(10Z,13Z,16Z)/16:2(9Z,12Z)) is a phosphatidylinositol phosphate. Phosphatidylinositol phosphates are acidic (anionic) phospholipids that consist of a phosphatidic acid backbone, linked via the phosphate group to a phosphorylated inositol (hexahydroxycyclohexane). Phosphatidylinositol phosphates 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 phosphates 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. PIP(22:3(10Z,13Z,16Z)/16:2(9Z,12Z)), in particular, consists of one chain of (10Z,13Z,16Z-docosatrienoyl) at the C-1 position and one chain of (9Z,12Z-hexadecadienoate) at the C-2 position. The (10Z,13Z,16Z-docosatrienoyl) moiety is derived from fish oils, while the (9Z,12Z-hexadecadienoate) moiety is derived from fish oils. The most important phosphatidylinositol phosphate in both quantitative and biological terms is phosphatidylinositol 4-phosphate. Phosphatidylinositol and the phosphatidylinositol phosphates are the main source of diacylglycerols that serve as signaling molecules, via the action of phospholipase C enzymes. Phosphatidylinositols phosphates are usually present at low levels only in tissues, typically at about 1 to 3% of the concentration of phosphatidylinositol. [HMDB]
