Alpha-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.
tocopherol
Yes, but vitamin E is written as "Alpha Tocopherol" in chemical formula.
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
