General description

Inositol phospholipid species are membrane-bound signaling molecules that have been implicated in almost all aspects of cellular physiology, including cellular growth, metabolism, proliferation, and survival.

Phosphatidylinositol (PI) is a phospholipid which accounts for 10% of the lipid in the cells of eukaryotes. 18:1 PI (1,2-dioleoyl-sn-glycero-3-phospho-(1′-myo-inositol)/ DOPI) is an anionic phospholipid.


18:1 PI (1,2-dioleoyl-sn-glycero-3-phospho-(1′-myo-inositol)/ DOPI) has been used to prepare lipid mix giant unilamellar vesicles (LM-GUVs).

Biochem/physiol Actions

Phosphatidylinositol (PI) can serve as a precursor for inositol phosphates, that are soluble in water. 18:1 PI (1,2-dioleoyl-sn-glycero-3-phospho-(1′-myo-inositol)/ DOPI) may serve as a substrate for lysosomal phospholipase A2 (LPLA2) and can promote LPLA2 activity.
