The official definition for the word tocopherol is "any of several closely related compounds, found in wheat germ oil, egg yolk, and leafy vegetables, that collectively constitute vitamin E. They are fat-soluble alcohols with antioxidant properties, important in the stabilization of cell membranes."
E
cholecalciferol. Or it could be calciferol.
The chemical name of Vitamin E is tocopherol.
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.
tocopherol
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).
Tocopheryl acetate, also known as vitamin E acetate, is a common vitamin supplement with the molecular formula C31H52O3. It is the ester of acetic acid and tocopherol (vitamin E).
Alpha-tocopherol is considered the most powerful and abundant form of vitamin E in the human body. It is a fat-soluble antioxidant that helps protect cells from damage caused by free radicals.
