    Oxidative Prozesse in Linsen verschiedener dominanter Kataraktmutanten der Maus

    Oxidative Prozesse spielen neben osmotischen Prozessen und Veränderungen der Kristalline eine bedeutende Rolle bei der Kataraktentstehung (s. J. Graw: ,,Beteiligung oxidativer Prozesse bei der Kararaktentstehu...

    Bedeutung und Wirkungsweise von Antioxidanzien

    Aus den Beiträgen von Flohé, Saran und Elstner läßt sich entnehmen, daß aufgrund ihrer Reaktivität verschiedenste schädliche Wirkungen von Sauerstoffradikalen ausgehen. Es ist nun gleicherweise anzunehmen, daß...

    Determination of sulfite radical (SO 3 ⋅ −) reaction rate constants by means of competition kinetics

    The sulfite radical anion (SO 3 ⋅ −) was found to react rapidly with the flavonoid quercetin (k = 2.5 × 108 dm3mol−1 s−1) and the carotenoids crocin (k = 1.0 ×...

    Radical reactions in vivo - an overview

    Generation of radicals in vivo depends on metabolic activities. The reactions are usually influenced by(i) the presence and concentration of oxygen;(ii) the availability of transition metals (effects of binding a...

    Direct and indirect measurements of oxygen radicals

    Instead of covering the available detection methods in detail it is attempted to highlight the ambiguities inherent in oxygen radical detection under in vivo conditions. Due to physicochemical properties of th...

    Structural Principles of Flavonoid Antioxidants

    Flavonoids are the most ubiquitous and structurally evolved class of plant phenolic compounds. Based on a few principal structures (see Fig. 1), multitudinous hydroxylation, methoxylation, and glycosylation pa...

    Screening for Plant Antioxidants

    Chloroplasts of green plants produce oxygen by light-driven reactions and contain photodynamically active molecules which catalyze photo-oxidations. The latter processes and unavoidable leakage of electrons, r...

    Moderate antioxidative efficiencies of flavonoids during peroxidation of methyl linoleate in homogeneous and micellar solutions

    The relative reactivities as well as the stoichiometric coefficients for a number of flavonoids, catechols, and—for comparison—standard phenolic antioxidants were determined by analyzing the kinetics of oxygen...
