Vitamin E By Lauren Gervase

Vitamin E Vitamin E is also known as: Alpha-tocopherol, tocopherol, tocotrienol

Tocopherol Chemical Composition The term tocol is the trivial designation for 2-methyl-2-(4,8,12-trimethyltridecyl)chroman-6-ol (I, R1 = R2 = R3 = H) 1.3. Tocopherol(s). The term tocopherol(s) should be used as a generic descriptor for all mono, di, and trimethyltocols. Thus, this term is not synonymous with the term vitamin E.

Tocopherol Chemical Composition

Functions of Vitamin E Antioxidant Regulates oxidation reactions Cell-membrane stability Protects polyunsaturated fatty acids and Vitamin A

Antioxidant Nutrients Vitamin E, as well as Vitamin C and beta-carotene play an important role in the body’s defense against oxidative damage. Antioxidants take free radicals and inactivate them. It is important that Vitamin E is in the tissues, such as the brain and lungs which contain polyunsaturated fats.
