Radikalhemmere

Radikalhemmere, also known as free radical scavengers or antioxidants, are molecules that can inhibit oxidation. Oxidation is a chemical reaction that can produce free radicals, leading to chain reactions that may damage cells. Radikalhemmere terminate these chain reactions by neutralizing free radicals, thus preventing further damage.

These compounds play a crucial role in protecting biological systems from oxidative stress, which is implicated in aging and various diseases. Naturally occurring radikalhemmere include vitamins such as vitamin C (ascorbic acid) and vitamin E (tocopherols), as well as compounds like glutathione and flavonoids. Many of these are obtained through diet.

In addition to biological roles, radikalhemmere are also used in industrial applications. For instance, they are added to foods and cosmetics to prevent spoilage and degradation caused by oxidation. The effectiveness of a radikalhemmer depends on its chemical structure and its ability to donate an electron to a free radical without becoming a pro-oxidant itself. Research continues to explore the complex mechanisms of action and therapeutic potential of various radikalhemmere.
