The molecule is a 1-phosphatidyl-1D-myo-inositol 3,4-bisphosphate in which the phosphatidyl acyl groups at positions 1 and 2 are both specified as hexadecanoyl (palmitoyl). It derives from a hexadecanoic acid. It is a conjugate acid of a 1,2-dihexadecanoyl-sn-glycero-3-phospho-(1D-myo-inositol-3,4-bisphosphate)(5-).
