Metabolite Identification
Common NameBeta-tocopherol
Descriptionbeta-Tocopherol, also known as β-tocopherol or 5,8-dimethyltocol, belongs to the class of organic compounds known as tocopherols. These 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. Thus, beta-tocopherol is considered to be a quinone. Based on a literature review a significant number of articles have been published on beta-Tocopherol.
