Liver PE has been used as a standard for the extraction of lipid from yeasts.

Liver PE is suitable for the preparation of liposomes.

ChEBI: 1-stearoyl-2-arachidonoyl-sn-glycero-3-phosphoethanolamine zwitterion is a phosphatidylethanolamine 38:4 zwitterion obtained by transfer of a proton from the phosphate to the primary amino group of 1-octadecanoyl-2-(5Z,8Z,11Z,14Z-icosatetraenoyl)-sn-glycero-3-phosphoethanolamine; major species at pH 7.3. It is a phosphatidylethanolamine 38:4 zwitterion and a 1-stearoyl-2-acyl-sn-glycero-3-phosphoethanolamine zwitterion. It is a tautomer of a 1-stearoyl-2-arachidonoyl-sn-glycero-3-phosphoethanolamine.

Phosphatidylethanolamine (PE) consists of a small polar head group with fatty acid chains. It is the second most?plenteous?glycerophospholipid in eukaryotic?cells.?PE is a non-bilayer forming phospholipid. It is found abundantly in the?mitochondria.

Phosphatidylethanolamine (PE) is involved in providing rigidity to the cell membrane?via hexagonal phase structures, which promote tight packing of the?membrane bilayer formed by?phosphotidylcholine.?It is also involved in the conversion of prions from the non-toxic?to toxic conformation. PE also?initiates the autophagosome formation by attaching covalently to the?autophagy?Atg8?protein.
