Oxidativer Stress wird definiert als ein 'Zustand, in dem die Oxidation die antioxidativen Systeme im Körper übersteigt, was zu einem Verlust des Gleichgewichts zwischen ihnen führt'. Er verursacht nicht nur gefährliche Ereignisse wie Lipidperoxidation und oxidative DNA-Schäden, sondern auch physiologische Anpassungsphänomene und die Regulierung der intrazellulären Signaltransduktion. Eine Oxidations-Reduktions-Reaktion (Redox) ist eine Art von chemischer Reaktion, bei der Elektronen zwischen zwei Spezies übertragen werden. Eine Oxidations-Reduktionsreaktion ist eine chemische Reaktion, bei der sich die Oxidationszahl eines Moleküls, Atoms oder Ions durch Aufnahme oder Abgabe eines Elektrons ändert. Redoxreaktionen sind häufig und für einige der grundlegenden Funktionen des Lebens von entscheidender Bedeutung, darunter Photosynthese, Atmung, Verbrennung und Korrosion bzw. Rostbildung... Die Bestimmung des oxidativen Stresses eines Individuums wird jetzt zu einer Priorität in der Krankheitsvorbeugung, da viele Studien darauf hinweisen, dass es einen engen Zusammenhang zwischen der Veränderung des antioxidativen Abwehrsystems und der Entwicklung von über 200 verschiedenen Pathophysiologien gibt, die von Atherosklerose bis hin zu Krebs, AIDS, entzündlichen Autoimmunerkrankungen und Diabetes reichen.
