Antioxidants such as tocotrienols may protect against atherosclerosis since tissue injury from free radicals is a final common pathway of damage in arterial disease. In this study, the effects of tocotrienols on serum cholesterol, lipid peroxides, and aorta atheroma were assessed in rabbits fed an atherogenic diet for 12 weeks. Tocotrienols were more effective than tocopherols in preventing inc...

AkzoNobel’s range of organic peroxides for the crosslinking of elastomers and thermoplastics is the world’s largest, including a number of organic peroxides for the production of PEX-a pipes and tubes. Our products are marketed under the well-known trademark of Trigonox. When producing PE pipes and tubes, frequently high density polyethylene (HDPE) is used. To further improve the product proper...

Recently the nature of the lone pair-lone pair interaction in cyclic and bicyclic peroxides as well as in ozonides has been investigated by means of photoelectron (PE) spectroscopy [1-8]. As anticipated from model calculations on simple peroxides [1, 6, 7], there is a correlation between the torsional angle of the R-O-O-R unit and the splitting of the first two bands [5-8]. To investigate the i...

When paroxysmal nocturnal hemoglobinuria (PNH) erythrocytes were exposed to H(2)O(2) they lysed excessively and formed greater than normal quantities of lipid peroxides when compared to red cells of normal subjects and patients with most types of hematologic disease. It was also shown that lytic sensitivity to acidified serum was related to the enhanced lytic sensitivity to H(2)O(2). If the lip...

The unusual stability of bis- and tris-peroxides contradicts the conventional wisdom - some of them can melt without decomposition at temperatures exceeding 100 °C. In this work, we disclose a stabilizing stereoelectronic effect that two peroxide groups can exert on each other. This stabilization originates from strong anomeric nO → σ*CO interactions that are absent in mono-peroxides but reintr...
