Solid-phase phosphatidylethanolamine synthesis
Reactive Polymers, 1989Abstract Dipalmitoylphosphatidylethanolamine(DPPE) was prepared from natural phosphatidylethanolamine (cephalin) and palmitic anhydride (PAh) by using polymer-supported trityl as a protective group for the ammo group of cephalin.

Plasmalogens (Pls) are widely distributed in the biological membrane of animals and certain anaerobic bacteria, but their functions in the cell membrane are still poorly understood. Decrease of phosphatidylethanolamine plasmalogen (PEPls) in the brain tissue of patients with Alzheimer's disease prompted us to investigate the effect of the membrane ...

Ubiquitination of phosphatidylethanolamine in organellar membranes
Molecular Cell, 2022The covalent conjugation of ubiquitin family proteins is a widespread post-translational protein modification. In the ubiquitin family, the ATG8 subfamily is exceptional because it is conjugated mainly to phospholipids. However, it remains unknown whether other ubiquitin family proteins are also conjugated to phospholipids.

Phosphatidylethanolamine N-methyltransferase from liver
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1997Phosphatidylethanolamine N-methyltransferase (PEMT) converts phosphatidylethanolamine to phosphatidylcholine. Most PEMT activity (PEMT1) is associated with endoplasmic reticulum. A second form of the enzyme (PEMT2) has been localized to the mitochondria-associated membrane. PEMT2 is a 22.5-kDa protein that has been purified from rat liver.

Adhesion between Phosphatidylethanolamine Bilayers
Langmuir, 1996The goal of this study is to provide additional information on the short-range interactions that determine the adhesion energy between bilayer surfaces. The specific problem concerns the hydration properties of bilayers of the membrane lipid phosphatidylethanolamine (PE), which imbibe much less water than bilayers composed of the other common ...

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, 1974Abstract 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 ...

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, 1988The 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, 2000Reports 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.
