They contribute to the destruction of various tissues from the skin resulting in wrinkles) to areas of the brain responsible for remembering information. To bind free radicals and, consequently, slow down the aging process help a particular substance, the so-called antioxidants. These include, in particular, include vitamins a, C and E, as well as a number of enzymes, and in particular, catalase and superoxide dismutase. The latter is considered the most effective, but their molecules, and molecules of enzymes in General, very large, so not able to penetrate through the cell membrane into the cells, which doctors wanted to cure.
