Selenium is the functional component of the enzyme gltathine peroxidase.
The enzyme assures the maintenance of the structural integrity of the liver and other cell membranes by protecting them from the destructive effects of free radicals. Oxygen radicals are formed during lipid metabolism, but also during exposure to ionizing radiation and certain drugs. Selenium is required for the maintenance of fertility, the functioning of the eye, the heart and immune system. It also exerts protective effects against certain heavy metals. All rights reserved.
