[Mechanism of action of vitamin E. Study of the interaction of vitamin E (alpha-tocopherol) and its analogs with fatty acids and their derivatives by fluorimetry].

Formation of a complex between alpha-tocopherol or its analogues in the excited state and fatty acids or their hydroperoxides has been suggested basing on the fluorescence quenching experimental data. The possible mechanism of the complex formation, its nature and role in the fatty acid peroxidation is discussed.
