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, R 1 = R 2 = R 3 = 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
