usage and synthesis

chemical properties

light yellow to brownish red liquid, clear, viscous oil. it has a mild, characteristic odour and taste, and its biological avtivity is three times higher than synthetic ve.

usage

vitamin e, antioxidant

α-tocopherol is the most bioactive of the naturally occurring forms of vitamin e. richest sources are green vegetables, grains, and oils, particularly palm, safflower and sunflower oils.
