Usage:vitaminE is used to refer to a group of fatsoluble compounds that include both tocopherols and tocotrienols.There are many different forms of vitamin E, of which γ-tocopherol is the most common in the North American diet. γ-Tocopherol can be found in corn oil, soybean oil, margarine and dressings.α-Tocopherol, the most biologically active form of vitamin E, is the second most common form of vitamin E in the North American diet. This variant of vitamin E can be found most abundantly in wheat germ oil, sunflower, and safflower oils. It is a fatsoluble antioxidant that stops the production of reactive oxygen species formed when fat undergoes oxidation.
