1.what is Tocopherol ?

Tocopherol is a naturally occurring chemical element found in a variety of foods. It is commonly called vitamin E in a generic sense, as vitamin E substances are made up of tocopherol and similar elements. The most common form of this element is called alpha- tocopherol. Tocopherol in the form of vitamin E is a regular part of the average diet, with specific recommended dosages available to the public from U.S. science institutions in the form of “recommended daily allowance” or RDA. Foods that include vitamin E will usually have the RDA printed on the nutritional label.

The tocotrienols have the same methyl structure at the ring and the same Greek letter-methyl-notation, but differ from the analogous tocopherols by the presence of three double bonds in the hydrophobic side chain. The unsaturation of the tails gives tocotrienols only a single stereoisomeric carbon whereas tocopherols have 3 centers.

2.Where Is Tocopherol Found?

The various kinds of substances labeled tocopherol or vitamin E are found in natural foods like spinach, nuts and vegetable oils. They are also present in some processed foods like breakfast cereals, where foods that were otherwise not high in vitamins are fortified with a variety of vitamins including vitamin E.
