   Manganese
   Obtained by reduction with aluminium or in a blast furnace. Pure manganese is a hard, brittle, silvery coloured, metallic element which exists in three polymorphic forms (alpha, beta and gamma) and has a complicated crystal structure. It resembles iron in being moderately reactive and dissolving in cold, dilute non-oxidising acids. When exposed to ...

   manganese
   An essential trace element. Present in cells as concentrations of around 0.01mM. Activates a wide range of enzymes eg. pyruvate carboxylase and one family of superoxide dismutases. Resembles magnesium and may replace it in many enzymes when it can modify substrate specificities. The addition of manganese salts to buffer solutions will often make cells very adhesive.

   Manganese
   `Manganese` is a chemical element that has the symbol `Mn` and atomic number 25. It is found as the free element in nature (often in combination with iron), and in many minerals. The free element is a metal with important industrial metal alloy uses. Manganese ions are variously colored, and are used industrially as pigments and as oxidation chemicals. Manganese (II) ions function as cofactors for a number of enzymes and the element is thus a req...
