General description

Phosphatidylethanolamine (PE) is a glycerophospholipid.


1-stearoyl-2-oleoyl-sn-glycero-3-phosphoethanolamine (18:0-18:1 PE) may be used:
  • as a component in monomolecular films domain formation and characterization
  • in the synthesis of mixed acyl chain 7-nitrobenz-2-oxa-1,3-diazol-4-yl-diacyl-sn-glycero-3-phosphoethanolamine (N-NBD-PE) and (N-lissamine rhodamine B sulfonyl)-diacyl-sn-glycero-3-phosphoethanolamine (N-Rh-PE) probes
  • in the preparation of liposomes

Biochem/physiol Actions

Phosphatidylethanolamine (PE) serves as a lipid chaperon. It is known to participate in the initiation of autophagy.

A major problem in defining biological membrane structure is deducing the nature and even existence of lipid microdomains. Lipid microdomains have been defined operationally as heterogeneities in the behavior of fluorescent membrane probes, particularly the fluorescence resonance energy transfer (FRET)...

In this work the properties of monomolecular films composed of 1-stearoyl-2-oleoyl-sn-glycero-3-phosphoethanolamine (SOPE) and cholesterol, differing in lipid proportion, were investigated in the context of domain formation in the inner leaflet of membrane. To perform comprehensive analysis of the studied model...

The glycerophospholipids phosphatidylcholine (PC) and phosphatidylethanolamine (PE) account for greater than 50% of the total phospholipid species in eukaryotic membranes and thus play major roles in the structure and function of those membranes. In most eukaryotic cells, PC and PE...

Imaging mass spectrometry (IMS) is becoming an essential technique in lipidomics. Still, many questions remain open, precluding it from achieving its full potential. Among them, identification of species directly from the tissue is of paramount importance. However, it is not...
