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.

Journal of Macromolecular Science, Part A, 2009
Monolayers of phosphatidylethanolamine (PE), cholesterol (Ch), phosphatidylcholine (PC), and binary mixtures (PC-PE or PE-Ch) were investigated at the air/water interface. The surface tension values of pure and mixed monolayers were used to calculate π -A isotherms.

Labeling Membranes with Fluorescent Phosphatidylethanolamine
Cold Spring Harbor Protocols, 2011INTRODUCTIONThe 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)).

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 ...

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 ...

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.

Studies on the thermotropic behavior of aqueous phosphatidylethanolamines
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1983The thermal response of aqueous dispersions of a series of synthetic saturated phosphatidylethanolamines was studied by differential scanning calorimetry and by infrared spectroscopy. Dispersions which had not been previously heated above tm, the temperature of the gel to liquid crystalline transition, showed transitions at a higher temperature, tm+h ...

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 ...

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.
