Phospholipid oxidation in emulsions
Lipids, 1970AbstractThe autoxidation of purified phosphatidyl ethanolamine (PE) and phosphatidyl choline (PC), extracted from egg and soybean lipids, was followed by oxygen uptake measurements in emulsified systems. All emulsified phospholipid fractions had comparable activation energies.

Oxidized phospholipids and isoprostanes in atherosclerosis
Current Opinion in Lipidology, 1998Lipid oxidation has been shown to be a prominent feature of atherosclerosis. The presence of isoprostanes and other lipid oxidation products has been clearly demonstrated in lesions. Furthermore, antibodies to oxidized phospholipids have been identified in animal and human models.

Bioactive phospholipid oxidation products
Free Radical Biology and Medicine, 2000Oxidation of phospholipids results in chain-shortened fragments and oxygenated derivatives of polyunsaturated sn-2 fatty acyl residues, generating a myriad of phospholipid products. Certain oxidation products of phosphatidylcholine bind to and activate the human receptor for PAF, and these PAF-like lipids are potent, selective inflammatory mediators ...

Determination of pyrrolized phospholipids in oxidized phospholipid vesicles and lipoproteins
Analytical Biochemistry, 2004The Ehrlich reaction was optimized to determine pyrrolized phospholipids produced as a consequence of oxidative stress. The procedure consisted of the treatment of the modified phospholipids with p-(dimethylamino)benzaldehyde at a controlled acidity temperature and the spectrophotometric determination of adducts produced.

Inflammatory profile of oxidized phospholipids
Thrombosis and Haemostasis, 2007SummaryLipid oxidation products and in particular oxidized phospholipids (OxPL) are increasingly recognized as inducers of chronic inflammation characteristic of atherosclerosis. OxPL stimulate production of chemokines and adhesion of monocytes to endothelial cells.

Mediation of Apoptosis by Oxidized Phospholipids
2008Free radical-mediated oxidation of (poly)unsaturated glycerophospholipids in membranes and lipoproteins leads to the formation of a plethora of products. Some of these oxidized phospholipids, especially the truncated forms, induce apoptosis depending on their chemical structure, concentration and cell type.

Oxidation of Unsaturated Phospholipids: A Monolayer Study
Langmuir, 2020Lipid oxidation does strongly influence the self-organization of plasma membranes; the detailed influence is not yet clear. In this work, phospholipid monolayers at the air/water interface were used as model membranes. Oxidation was induced by the reactive oxygen species formed in a H2O2-enriched solution. The reaction was found to be diffusion-limited;

[Oxidized phospholipids and atherosclerosis].
Sheng li xue bao : [Acta physiologica Sinica], 2021Phospholipids are important components of biomembrane and lipoproteins. Phospholipids can be oxidized by free radicals/nonradicals and enzymes to form oxidized phospholipids (OxPLs), which can lead to further generation of oxidation products with different biological activities.

Chromatographic analysis of phospholipid and cholesterol oxidation
Talanta, 1984Capillary thin layer and gas chromatographic methods for analysis of the extent of oxidation in phosphatidyl choline/cholesterol samples are described. Examples of systems suitable for qualitative and quantitative analysis, based on use of unmodified samples or of their derivatives, are illustrated. A method for concurrent quantitative determination of
