Vitamin E: molecular and biological function.
There is a growing body of evidence implicating free radicals in a wide variety of medical diseases and conditions, especially the diseases of ageing, such as cancer and cardiovascular disease, which appear to be ultimate expressions of long-term, cumulative and sustained cellular damage. Vitamin E is an excellent lipid-soluble, chain-breaking antioxidant in the presence of other co-operative a...
متن کاملVitamin E: function and metabolism.
Although vitamin E has been known as an essential nutrient for reproduction since 1922, we are far from understanding the mechanisms of its physiological functions. Vitamin E is the term for a group of tocopherols and tocotrienols, of which alpha-tocopherol has the highest biological activity. Due to the potent antioxidant properties of tocopherols, the impact of alpha-tocopherol in the prevent...
متن کاملVitamin D: concerning the relationship between molecular topology and biological function.
Structure-function relationships for vitamin D, its metabolites, and analogs are discussed with particular emphasis on the A-ring conformation. It is emphasized that the A-ring of these seco-steroids consists of a pair of rapidly equilibrating chair conformers. As a consequence, different chair conformations produce different orientations of substituent groups in the A-ring. It is proposed that...
متن کاملThe Benefits of vitamin E on liver function and the hemopoietic System in thalassemia Patients
Abstract Background β−Thalassemic children have oxidative stress and antioxidant deficiency even without iron overload status. In these patients, tissue damage due to oxidative stress may be occurred. Also, it seems that thalassemic patients have higher levels of ALT, AST therefore, the main aim of the present study was to determine the benefits of vitamin E as an antioxidant supplements in β...
متن کاملVitamin E--its role in neurological function.
Studies in patients with abetalipoproteinaemia, other chronic and severe fat malabsorptive states and a selective defect in vitamin E absorption, together with neuropathological studies in the vitamin E deficient human, monkey and rat indicate that vitamin E is important for normal neurological function. Appropriate vitamin E supplementation is, therefore, advisable for all patients with chroni...
