[Effect of vitamin E on the synthesis of polyunsaturated fatty acids (author's transl)].

The formation of polyunsaturated fatty acids is influenced by vitamin E. The enzyme of the endoplasmic reticulum isolated from rat liver responsible for chain elongation and desaturation showed higher activity under vitamin E-deficiency. The activity was raised both per mg protein and per mg DNA. The application of alpha-Tocopherol to the vitamin E-deficient animals caused the normalization of the enzyme activity within 48 hours. This indicates a regulatory function of alpha-Tocopherol in the process of oxidation.
