Tocopherol Behavior and Membrane Constituents in Erythrocytes with Oxidant Stress
Recently, toxicity caused by oxygen and its active species has received much attention in connection with a variety of pathological events.1 However, the mechanism responsible for the peroxidation of biomembranes is still unclear. Tocopherols (vitamin E) are located in the membranes and act there as an only chain-breaking antioxidant.2,3 When biomembranes are damaged mainly by a free radical chain oxidation,4 the effects of tocopherols will be spotlighted. Nevertheless, the mechanisms by which membrane tocopherols inhibit the peroxidation still require detailed study, partly because the active species and the sites of their generation have not usually been known or controlled.
