**11.9 Tocopherol and tocotrienols**

 Vitamin E is fat soluble vitamin with antioxidant properties, and a collective set of eight related tocopherol and tocotrienols [75]. α-Tocopherol is one of the most important lipid soluble antioxidant and it protect the cell membrane from oxidant by reacting with lipid radicals which are formed in lipid peroxide chain reaction [76]. These free radical intermediates are then removed and prevents the propagation reaction from continuing. In this reaction oxidized α-tocopherol radicals are formed which recycled back to the active reduced form through reduction reaction by other antioxidants such as vitamin-A, etc. [77]
