THE ANTIOXIDANTS

Deprivation of the opportunity to form free radicals is one of the main roads of prolonging the life. To the fat-soluble organic oxidants refer vitamin E (tocopherol), vitamins of group P (flavonoids), phospholipids, vitamins of group K, bilirubin, biliverdin, ubiquinone, steroid hormones. To the water-soluble organic oxidants refer vitamin C, citric acid and nicotinic acid, sulphur-containing amino acids (cysteine, glutathione), catechins and benzoic acid. Of synthetic antioxidants in medicine are used barbiturates and organic sulphur compounds. B vitamins also have antioxidant properties. Of interest is the fact that in females the content of organic antioxidants (vitamin C - ascorbic acid) in the serum of the blood is higher than in men. This is an attempt to explain the higher average life expectancy for women. The same is true for vitamin E, the amount of which is approximately two times higher in women. Moreover the role of vitamin E in bioenergetic processes in aging is undeniable. Its deficiency leads to a wide variety of pathological manifestations. The offenses in bioenergetic processes in the cell are most important. Particularly important are the properties of alpha-tocopherol to influence the activity of the enzyme systems in the tissues of a living organism. Similar to the properties of vitamin E are also some organic and inorganic compounds of selenium, vitamin C and others which have antioxidant properties and preserve the sulfhydryl groups of cysteine and glutathione (composed of the amino acids - glutamate, cysteine and glycine). These are citric, fumaric, pyruvic, alpha-beta-glutaric acid, and some minerals.

On the other hand in the body decrease the reserve capacity for providing more sulfhydryl groups. This supports the view for eventual introduction into the body of thiol compounds and amino acids containing sulphur, cystine, cysteine, methionine. It is assumed that the thiol compounds are a kind of protector that protects the genetic apparatus of premature aging.
