In biochemistry, vitamin E is a "generic descriptor for all tocopherols and tocotrienols that exhibit alpha-tocopherol activity. by virtue of the phenolic hydrogen on the 2h-1-benzopyran-6-ol nucleus, these compounds exhibit varying degree of antioxidant activity, depending on the site and number of methyl groups and the type of isoprenoids."[2]
