Influence of retinoids on phosphatidylethanolamine lipid polymorphism
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1992The 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 ...

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 ...

Phosphatidylethanolamine: Structural Component and Beyond
Current Molecular MedicineAbstract: 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 ...

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 ...

The possible functional significance of phosphatidylethanolamine methylation
Nature, 1980The 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 ...

A convenient synthesis of phosphatidylethanolamines
Chemistry and Physics of Lipids, 1967Silver-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.

Stabilization of phosphatidylethanolamine hydroperoxides in human plasma
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1989When phosphatidylcholine hydroperoxides (PC-OOH) and phosphatidylethanolamine hydroperoxides (PE-OOH) were incubated in normal saline at 37 degrees C, PE-OOH were decomposed more rapidly than PC-OOH, possibly due to Fe2+-binding ability of their polar head-group. In human plasma, both phospholipid hydroperoxides were stable during incubation.

Phosphatidylcholine homeostasis in phosphatidylethanolamine-depleted Tetrahymena
Archives of Biochemistry and Biophysics, 1986The relative contributions of the two pathways of phosphatidylcholine biosynthesis, phosphatidylethanolamine N-methyltransferase (EC 2.1.1.17) and diacylglycerol: CDP-choline cholinephosphotransferase (EC 2.7.8.1), are altered in the ciliate protozoan Tetrahymena thermophila whose phospholipid composition has been modified by culturing the organism in ...
