Tocopherol is a type of vitamin E. It has E number E307. Vitamin E exists in eight different forms, four tocopherols and four tocotrienols. All feature a chromane ring, with a hydroxyl group that can donate a hydrogen atom to reduce free radicals and a hydrophobic side chain which allows for penetration into biological membranes. Compared to the others, tocopherol is preferentially absorbed and accumulated in humans. For price, specification and other details please contact us
