Wikipedia Article(s)

Tocopherols (or TCP) are a class of chemical compounds of which many have vitamin E activity. It is a series of organic compounds consisting of various methylated phenols. 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” and “φέρειν”, [to bear or carry meaning in sum "to carry a pregnancy," with the ending "-ol" signifying its status as a chemical alcohol. Tocotrienols, which are related compounds, may also have vitamin E activity. All of these various derivatives with vitamin activity may correctly be referred to as "vitamin E." Tocopherols and tocotrienols are fat-soluble antioxidants but also seem to have many other functions in the body. The compound α-tocopherol, a common form of tocopherol added to food products, is denoted by the E number E307. Read more... or Edit at Wikipedia...
