The chemical name of Vitamin E is tocopherol.
cholecalciferol. Or it could be calciferol.
E
Alpha-tocopherol is a version of vitamin E that contains no double bonds. When alpha-tocopherol is delivered to the liver via chylomicron reminants it binds to a binding protein to become rrr-alpha-tocopherol. RRR-alpha-tocopherol is incorporated into VLDL (very low density lipoproteins) membranes and is delivered to perpherial tissues and to LDL. RRR-alpha-tocopherol acts as an antioxidant to prevent polyunsaturated fatty acids from oxidation within VLDL and LDL. Without rrr-alpha-tocopherol oxidation of this fatty acids can occur and cause atherosclerosis.
Alpha-tocopherol is the form of tocopherol that exhibits vitamin E activity in the human body. It is the most biologically active form of vitamin E and is the form typically found in supplements and fortified foods.
Eight forms of vitamins E are known; see the link below for details.
tocopherol
The scientific name for Vitamin E is tocopherol. It is a group of fat-soluble compounds with antioxidant properties that are essential for human health.
It is organic molecule.
The term Vitamin E is used. Or if you want to talk biochemistry then tocopherol (mainly alpha-tocopherol, but it includes a group of similar chemicals).
Tocopherol and tocotrienol
Tocopherol is naturally-occurring, while tocopheryl acetate is synthetic. Both are used in cosmetics as antioxidants, keeping oils from turning rancid, and for their reported benefits on skin (healing, anti-aging).
