Oxidation of o-dihydroxyphenols by catalase and its application to the colorimetric determination and visualization of catalase on polyacrylamide gel

Is the autoxidation of catecholamines involved in ischemia-reperfusion injury?

The autoxidation of catecholamines has been proposed to be a source of oxygen radicals in ischemia-reperfusion injury. However, this autoxidation per se is extremely slow at physiological pH and therefore is unlikely to be a primary source of oxygen radicals in ischemia-reperfusion injury. On the other hand, oxygen radicals from catecholamines are more likely to arise through catalyzed oxidations involving enzymatic systems and/or metal ions. It is these latter reactions that may be of interest with respect to damage associated with ischemia-reperfusion injury.
