mangosteen, anthioksidan

Anthioksidan mangosteenSpace filling model of the antioxidant glutathione. Yellow ball is sulfur atom that provides antioxidant activity, when the red ball, blue, white, and gray represents oxygen atom, nitrogen, hydrogen, and carbon, respectively.

Antioxidants are substances that can slow or prevent the oxidation process
This substance is actually able to slow or inhibit the oxidation of easily oxidized substances even in low concentrations. Antioxidants are also suitable defined as compounds that protect cells from harmful effects of reactive oxygen free radicals when it comes to disease, free radicals can be derived from the metabolism of the body and other external factors. Free radicals
are unstable species that have unpaired electrons and the search for electron pairs in macromolecules biologi.Protein lipids and DNA from healthy human cells is a good source of electron pairs. Oxidation conditions can cause damage to proteins and DNA, cancer, aging, and other diseases. Chemical components which act as antioxidants are polyphenolic compounds and phenolic groups.Compounds of this class there are many dialam, especially in plants, and has the ability to capture free radicals. Antioxidants are found in many foodstuffs, such as vitamin E, vitamin C, and carotenoids.Antioxidants are expected to secure the use or non-toxic, effective at low concentrations (from 0.01 to 0.02%), available at affordable prices, and are resistant to the processing of the product. Antioxidants are important in fighting free radicals, but the excess capacity of the cell damageBased on its origin, consisting of antioksigen antioxidant derived from the body (endogenous) and outside the body (exogenous). Sometimes the endogenous antioxidant systems are not quite able to cope with excessive oxidative stress. Oxidative stress is the current state of antioxidant mechanisms are not sufficient to break down reactive oxygen species. Therefore, the necessary antioxidants from the outside (exogenous) to overcome them.
