Chemical Information
FooDB Nameδ-tocopherol
DescriptionD-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. D-tocopherol is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). D-tocopherol can be found in a number of food items such as sorghum, common oregano, channel catfish, and multigrain bread, which makes D-tocopherol a potential biomarker for the consumption of these food products. Tocopherols (TCP) are a class of organic chemical compounds (more precisely, various methylated phenols), many of which have vitamin E activity. Because the vitamin activity was first identified in 1936 from a dietary fertility factor in rats, it was given the name "tocopherol" from the Greek words "τόκος" [tókos, birth], and "φέρειν", [phérein, to bear or carry] meaning in sum "to carry a pregnancy," with the ending "-ol" signifying its status as a chemical alcohol .
