Manganese Superoxide Dismutase (MnSOD) - …

MnSOD is a Redox Catalyst. The Mn superoxide dismutase (MnSOD) is the only SOD enzyme located in the mitochondrial matrix. Mitochondria are the location of many biological processes reducing O 2, producing an influx of O 2 ˙radicals. 1,3 The cofactor of the MnSOD protein is manganese (Mn). 1 The Mn changes between its 3+ and 2+ oxidation states within the dismutase mechanism, consisting of ...

Iron and Manganese Removal — Publications

Manganese acts in a similar way but causes a brownish-black stain. Soaps and detergents do not remove these stains, and the use of chlorine bleach and alkaline builders (such as sodium carbonate) can intensify the stains. Iron and manganese deposits will build up in pipelines, pressure tanks, water heaters and water softeners.
