Journal ArticleDOI
Radiation-induced peroxidation and fragmentation of lipids in a model membrane
TL;DR: Comparable radiation-chemical yields of conjugated-diene products and phosphatidic acid indicate that the probabilities of oxidation and fragmentation processes to occur are approximately equal in this case.
Journal ArticleDOI
Formation of phosphatidic acid, ceramide, and diglyceride on radiolysis of lipids: identification by MALDI-TOF mass spectrometry.
TL;DR: It has been shown that gamma irradiation of such glycolipids as cerebroside and galactosyl diglyceride leads to formation of ceramide and diglycerides, respectively, and an assumption was made that, owing to radiation-induced free radical fragmentation of lipids in their polar moiety, formation of signaling molecules can occur.
Journal ArticleDOI
Chemistry of C-2 Glyceryl Radicals: Indications for a New Mechanism of Lipid Damage
TL;DR: It was found that cleavage of the β-C,O bond proceeds rapidly, if a hydroxyl group is present at the radical carbon center, and a concerted elimination mechanism is suggested.
Journal ArticleDOI
Quinones as Free-radical Fragmentation Inhibitors in Biologically Important Molecules
Oleg I. Shadyro,G. K. Glushonok,T. G. Glushonok,I.P. Edimecheva,A.G. Moroz,A. A. Sosnovskaya,I. L. Yurkova,G. I. Polozov +7 more
TL;DR: It is suggested that the system quinone/diphenol is able to not only deactivate or generate such active species as O 2 ” m but also control the realization probability of free-radical processes of peroxidation and fragmentation in biologically important molecules.
Journal ArticleDOI
Homolytic Cleavage of the O-glycoside Bond in Carbohydrates: A Steady-state Radiolysis Study
TL;DR: Oxygen, quinones and compounds capable of forming quinoid structures were found to inhibit radiation-induced homolytic destruction processes taking place in glycosides, di- and polysaccharides.
