Vitamin E refers to a group of eight fat-soluble compounds that include both tocopherols and tocotrienols.
[1] Of the many different forms of vitamin E, γ-tocopherol is the most common in the North American diet.
[2] γ-Tocopherol can be found in corn oil, soybean oil, margarine, and dressings.
[3] In the North American diet, α-tocopherol, the most biologically active form of vitamin E, is the second-most common form of vitamin E. This variant can be found most abundantly in wheat germ oil, sunflower, and safflower oils.
[4] As a fat-soluble antioxidant, it stops the production of reactive oxygen species formed when fat undergoes oxidation.
1. As an antioxidant, vitamin E acts as a peroxyl radical scavenger, preventing the propagation of free radicals in tissues, by reacting with them to form a tocopheryl radical, which will then be reduced by a hydrogen donor (such as vitamin C) and thus return to its reduced state.
2. As an enzymatic activity regulator, for instance, protein kinase C (PKC), which plays a role in smooth muscle growth, can be inhibited by α-tocopherol.
3. Vitamin E also has an effect on gene expression. Macrophages rich in cholesterol are found in the atherogenetic tissue.
4. Vitamin E also plays a role in neurological functions,and inhibition of platelet aggregation
5. Vitamin E also protects lipids and prevents the oxidation of polyunsaturated fatty acids.
