Vitamin E (alpha-tocopherol) was first isolated from plant oils. The term tocopherol was used to name the initial four compounds that shared a similar structure: a complex ring and a long saturated side chain. Tocopherols are the primary fat-soluble antioxidants that help minimize the effects of free-radicals. Of the four compounds designated as alpha-, beta-, gamma-, and delta- tocopherols alpha-tocopherol has been shown to have the greatest nutritional and biological value. Vitamin E (alpha-tocopherol) may help: Prevent polyunsaturated fatty acids from breakin down (oxidizing) and combining with substances that may harm the body.
