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 ...

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 ...

Effect of Phosphatidylethanolamine and Oleic Acid on Membrane Fusion: Phosphatidylethanolamine Circumvents the Classical Stalk Model

The Journal of Physical Chemistry B, 2021
Membrane fusion is one of the most important processes for the survival of eukaryotic cells and entry of enveloped viruses to the host cells. Lipid composition plays a crucial role in the process by modulating the organization and dynamics of the membrane, as well as the structure and conformation of membrane proteins.

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 ...

Anti-phosphatidylethanolamine (aPE) Antibodies: a Survey

Journal of Autoimmunity, 2000
Reports of anti-phosphatidylethanolamine antibodies (aPE) with similar or identical pathogenic associations as those described for anticardiolipin (aCL) and anti-phosphatidylserine (aPS) are found in the literature. In some instances, aPE is the sole antiphospholipid antibody (aPL) observed.

Roles for the methylation of phosphatidylethanolamine

Current Opinion in Lipidology, 1998
The methylation of phosphatidylethanolamine is an auxiliary pathway for phosphatidylcholine biosynthesis in liver. Two forms of the enzyme, phosphatidylethanolamine N-methyltransferase, which catalyses this reaction, are located on the endoplasmic reticulum and mitochondria-associated membranes.

Labeling Membranes with Fluorescent Phosphatidylethanolamine

Cold Spring Harbor Protocols, 2011
INTRODUCTIONThe phospholipid phosphatidylethanolamine (PE) can be conjugated via its head group to a number of fluorophores, including rhodamine, BODIPY (boron-dipyrromethene; 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene), and NBD (N-(7-nitrobenz-2-oxa-1,3-diazole-4-yl)).

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

Liquid crystalline phases of hydrated phosphatidylethanolamine

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1969
Abstract In order to investigate liquid crystalline phases of hydrated phosphatidylethanolamine by electron microscopy, a negative staining technique was used. Since the presence of the different phases is a function of lipid concentration and temperature, the phosphatidylethanolamine-water system was studied at different states of swelling at ...

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.
