The molecule is a 1-phosphatidyl-1D-myo-inositol 4-phosphate(3-) arising from deprotonation of all three free phosphate OH groups of 1,2-dioctanoyl-sn-glycero-3-phospho-(1D-myo-inositol-4-phosphate); major species at pH 7.3. It is a conjugate base of a 1,2-dioctanoyl-sn-glycero-3-phospho-(1D-myo-inositol-4-phosphate).
