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.

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.

RATIONALE Nonenzymatic glycation of phosphatidylethanolamines (PEs) seems to a have a role in angiogenesis and atherosclerosis. Glycated PEs are more easily oxidized, enhancing oxidative stress.

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 ...

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

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.

A Fourier-transform infrared spectroscopic study of the thermotropic behavior of egg yolk phosphatidylethanolamines is reported. Two phase changes were monitored, the gel to liquid-crystalline acyl chain melting transition, centered at 12 degrees C, and ...

In vitro glycation and glycoxidation of phosphatidylethanolamines
Free Radical Biology and Medicine, 2014Formation and accumulation of advanced glycation end products (AGEs) appear to correlate with many human diseases, such as atherosclerosis and inflammation. Whereas AGE-modified proteins relatively well studied, aminophospholipid AGE-adducts have been less intensively investigated.
