PIP(18:1(15Z)/20:1(11Z)) belongs to the family of glycerophosphoinositol phosphates, which are lipids containing a common glycerophosphate skeleton linked to at least one fatty acyl chain and an inositol-5-phosphate moiety. Their general formula is O[C@H]1[C@H](O)[C@@H](O)[C@H](OP(O)(=O)OC[C@@H](CO(R1))O(R2))[C@H](OP(O)(O)=O)[C@@H]1O, where R1-R2 are fatty acid chains PIP(18:1(15Z)/20:1(11Z)) is made up of one 15Z-octadecenoyl(R1). Derivatives of phosphatidic acids in which the phosphoric acid is bound in ester linkage to the hexahydroxy alcohol, myo-inositol. Complete hydrolysis yields 1 mole of glycerol, phosphoric acid, myo-inositol, and 2 moles of fatty acids. (PubChem) [HMDB]
