Thermotropic behavior of phosphatidylethanolamine-cholesterol and phosphatidylethanolamine-phosphatidylcholine-cholesterol mixtures

Biochemistry, 1980
The thermotropic behavior of aqueous dispersions of phosphatidylethanolamine-cholesterol and phosphatidyl-ethanolamine-phosphatidylcholine-cholesterol mixtures has been studied by high-sensitivity differential scanning calorimetry. The gel to liquid-crystalline phase transition of phosphatidylethanolamines is broadened and shifted to lower temperature ...

Bioactive aldehyde-modified phosphatidylethanolamines

Biochimie, 2013
Lipid peroxidation generates a variety of lipid aldehydes, which have been recognized to modify protein and DNA, causing inflammation and cancer. However, recent studies demonstrate that phosphatidylethanolamine (PE) is a major target for these aldehydes, forming aldehyde-modified PEs (al-PEs) as a novel family of mediators for inflammation.

Phosphatidylethanolamine – in a pinch

Trends in Cell Biology, 2000
Cells actively modulate the lipid composition of the cytoplasmic and outer leaflets of their membranes. Plasma membranes, for example, contain the aminophospholipids phosphatidylethanolamine (PtdEtn) and phosphatidylserine (PtdSer) mainly in the cytoplasmic side of the bilayer.

Influence of retinoids on phosphatidylethanolamine lipid polymorphism

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1992
The interaction of all-trans-retinoic acid and all-trans-retinol with dielaidoylphosphatidylethanolamine has been studied by differential scanning calorimetry and 31P-NMR spectroscopy. Increasing concentrations of all-trans-retinoic acid up to a mol fraction of 0.09 were found to induce shifts to lower temperatures of both the L beta to L alpha and L ...

Phosphatidylethanolamine: Structural Component and Beyond

Current Molecular Medicine
Abstract: Phosphatidylethanolamine (PE) is a major phospholipid in biological membranes and plays essential roles in autophagy, cell signaling, protein function, and membrane integrity. Its dynamic, conical structure supports membrane fluidity and curvature, which are crucial for processes such as signaling ...

Synthesis of radio-isotopically labelled phosphatidylethanolamines

Chemistry and Physics of Lipids, 1974
Abstract The total chemical synthesis of di and tri-radioisotopically labelled 1–2 dipalmitoyl-sn-glycero-3-phosphorylethanolamine (PE) labelled with 14C-(diacyl) and 32P and 14C-(diacyl), 32P and 3H-(ethanolamine) are described. Due to the short half-life of the 32P isotope in the time consuming synthesis of the intramolecularly tri-labelled ...

A convenient synthesis of phosphatidylethanolamines

Chemistry and Physics of Lipids, 1967
Silver-t-butyl-(N-t-butyloxycarbonyl-2-aminoethyl) phosphate was synthesized. Coupling of this compound with 1-palmitoyl-2-oleoyl-glycerol-3-iodohydrin, followed by removal of both protecting groups, gave, after recrystallization (without chromatography) pure 1-palmitoyl-2-oleoyl-3-phosphatidylethanolamine in 55% yield.

The possible functional significance of phosphatidylethanolamine methylation

Nature, 1980
The conversion of phosphatidylethanolamine to phosphatidylcholine was first reported in rat liver microsomes by Bremer and Greenberg. The reaction requires three successive methylations of the ethanolamine moiety by S-adenosylmethionine. The highest activity for this enzyme has been found in liver microsomes and the enzyme from rat liver was recently ...

Angiogenic Potency of Amadori‐Glycated Phosphatidylethanolamine

Annals of the New York Academy of Sciences, 2005
Abstract: Glycation has been thought to participate in diabetic vascular diseases. However, there are no reports about the effects of lipid glycation on endothelial dysfunction. In this study, we have evaluated whether Amadori‐glycated phosphatidylethanolamine (Amadori‐PE), a lipid‐linked glycation compound, affected proliferation, migration, and tube

Extended hydrogen-bonded structures of phosphatidylethanolamine

Chemistry and Physics of Lipids, 1988
The structure of phosphatidylethanolamine in pure dry hexane was studied. Viscosity measurements show that the hexane solution of PE has a very high viscosity, while freeze fracture electron microscopy revealed extensive fibre-like structures. These extended structures are disrupted by the addition of small amounts of water or organic solvents which ...
