Introduction. Manganese (Mn) is an essential element in virtually all living organisms where it can fulfill two different functions: acting as an enzyme cofactor or as a metal with catalytic activity in biological clusters (Andresen et al., 2018).In humans, Mn functions as a cofactor for a variety of enzymes, including arginase, glutamine …

Manganese (Mn) is the twelfth most abundant element in the Earth's crust. Amongst some 300 minerals containing manganese, only about a dozen are of economic significance. Manganese is a silvery-gray metal that resembles iron. It is hard and very brittle, difficult to fuse, but easy to oxidize. Manganese metal and its common ions are paramagnetic.
