INTERACTION OF VITAMIN-E (ALPHA-TOCOPHEROL) WITH OXYGENATED DERIVATIVES OF FATTY-ACIDS

Fluorescence spectra of alpha-tocopherol and its mixtures with oxygena ted derivatives of fatty acids - linoleic acid hydroperoxide, hydroxyl inoleic and ricinoleic acids - were investigated in terms of the excit ation and emission dependence on the concentration of components in ac etonitrile solution. In accordance with our results, formation of the alpha-tocopherol eximer and exiplex with the oxygen-containing derivat ives of polyunsaturated fatty acids was suggested. The character of th e interaction between components of the excited complexes and their po ssible role in peroxidation of lipids are discussed.
