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 ...

AbstractCells of epithelial origin generally require ethanolamine (Etn) to grow in defined culture medium. When such cells are grown without Etn, the membrane phospholipid composition changes drastically, becoming phosphatidylethanolamine (PE)‐deficient due to a reduced de novo rate of PE synthesis, and growth stops.

Bioactive aldehyde-modified phosphatidylethanolamines
Biochimie, 2013Lipid 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.

Metabolism of phosphatidylethanolamine in the frog retina
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1980The synthesis and the turnover of phosphatidylethanolamine in frog retinal rod outer segments and microsomes were studied by monitoring the incorporation of five radioactive precursors: 32PO4, 33PO4 [3H]glycerol, [3H]serine, and [3H]ethanolamine. 1. Labeled serine was actively incorporated into phosphatidylethanolamine.

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.

Metabolism of chylomicron phosphatidylethanolamine in the rat
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 198410 min after intravenous injection of 32P-labelled chylomicrons 69% of the [32P]phosphatidylethanolamine, but only 34% of the [32P]phosphatidylcholine, was cleared from plasma. Over this time period the plasma phosphatidylethanolamine concentration that was increased after the chylomicron injection returned to normal, indicating that the rapid ...

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.

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 ...

Chemical methylation of phosphatidylethanolamine by S-adenosylmethionine
Biochemical and Biophysical Research Communications, 1985The chemical methylation of phosphatidylethanolamine (PE) by S-adenosyl methionine (SAM) is most active when carried out at alkaline pH's. Phosphatidylmonomethylethanolamine (PMME) and phosphatidyldimethylethanolamine are less effective reactants. The PE present in the microsomal and myelin membrane can serve as an acceptor in this reaction. Thin layer

Phosphatidylethanolamine – in a pinch
Trends in Cell Biology, 2000Cells 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.
