The molecule is a 1-phosphatidyl-1D-myo-inositol 5-phosphate(3-) obtained by deprotonation of the phosphate OH groups of 1,2-dilinoleoyl-sn-glycero-3-phospho-1D-myo-inositol 5-phosphate; major species at pH 7.3. It is a conjugate base of a 1,2-dilinoleoyl-sn-glycero-3-phospho-1D-myo-inositol 5-phosphate.
