Description | α-tocopherol is a member of the class of compounds known as tocopherols. Tocopherols are vitamin E derivatives containing a saturated trimethyltridecyl chain attached to the carbon C6 atom of a benzopyran ring system. The differ from tocotrienols that contain an unsaturated trimethyltrideca-3,7,11-trien-1-yl chain. α-tocopherol is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). α-tocopherol can be found in a number of food items such as lime, rowanberry, horseradish tree, and pineappple sage, which makes α-tocopherol a potential biomarker for the consumption of these food products. α-tocopherol is a form of vitamin E that is preferentially absorbed and accumulated in humans. The measurement of "vitamin E" activity in international units (IU) was based on fertility enhancement by the prevention of spontaneous abortions in pregnant rats relative to α-tocopherol . |
