Vitamin E: Introduction to Biochemistry and Health Benefits
by Lester Packer and Sharon Landvik
- Vitamin E serves as the major lipid-soluble chain-breaking anti-oxidant,
preventing lipid preoxidation and modulating the metabolism of the
arachidonic acid cascade initiated by lipoxygenase and/or cyclooxygenase.
- D-Alpha-tocopherol is the major biological dietary component with the most
prominent antioxidant activity as Vitamin E.
Preventions Using Vitamin E
- Vitamin E may help slow the peroxidative damage in the aging process.
- Reactive oxygen species have been implicated in the process of cancer
initiation. Research suggests anti-oxidants like Vitamin E may function
as anticarcinogens. Animal studies suggest Vitamin E decreases the
incidence of certain forms of cancer.
- Excessive platelet aggregation is a significant factor in the development
of atherosclerosis. Vitamin E significantly decreased this in induced
platelet aggregation and elevated platelet aggregation in patients with
high blood lipid levels and in oral contraceptive users. Helpful in
reducing free radical increase in coronary bypass surgery.
- ?????uous excercise depletes vitamin E in body tissues. Supplements
prevent reduction in performance in mountain climbers due to this.
- Vitamin E may be important component of lung's defense against
peroxidative damage, helping to protect against smoke and smog. Protects
?????? against harmful effects of pollution ??????? smokers.
