Introduction
Vitamin E refers to a group of eight fat-soluble compounds that include both tocopherols and tocotrienols.Of the many different forms of vitamin E, γ-tocopherol is the most common in the North American diet.γ-Tocopherol can be found in corn oil, soybean oil, margarine, and dressings. 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
