Vitamin E
Vitamin E BP98/USP24 Product Name:Vitamin E BP98/USP24Packing:25kgs/bagCAS NO:59-02-9Molecular Formula:C29h50o2Molecular Structure:Physico-chemical properties:White PowderPicture:Vitamin E is the collective name for a set of 8 related tocopherols and tocotrienols, which are fat-soluble vitamins with antioxidant properties. Of these, written as alpha-tocopherol has been most studied as it has the highest bioavailability, with the body preferentially absorbing and using this form.It has been claimed that α-tocopherol is the most important lipid-soluble antioxidant, and that it protects cell membranes from oxidation by reacting with lipid radicals produced in the lipid peroxidation chain reaction. This would remove the free radical intermediates and prevent the oxidation reaction from continuing. The oxidised α-tocopheroxyl radicals produced in this process may be recycled back to the active reduced form through reduction by other antioxidants, such as ascorbate, retinol or ubiquinol.The functions of the other forms of vitamin E are less well-studied, although gamma-tocopherol is a nucleophile that may react with electrophilic mutagens, and tocotrienols may have a specialized role in protecting neurons from damage. However, the roles and importance of the various forms of vitamin E are presently unclear, and it has even been suggested that the most important function of vitamin E is as a signaling molecule, and that it has no significant role in antioxidant metabolism.Most studies about Vitamin E have supplemented only alpha-tocopherol, but doing so leads to reduced serum gamma- and delta-tocopherol concentrations.
