Manganese is an essential trace element that is naturally present in many foods and available as a dietary supplement. Manganese is a cofactor for many enzymes, including manganese superoxide dismutase, arginase, and pyruvate carboxylase [ 1, 2 ]. Through the action of these enzymes, manganese is involved in amino acid, cholesterol, glucose ...
As two atoms of manganese react with one molecule of oxygen, the manganese reaction weight is twice times this, or 109.88. The molecular weight of oxygen is 31.999. The reaction ratio is thus (31.999) / (109.88), or 0.2912. This means that 0.2912 mg/l of oxygen is required for each mg/l of manganese (measured as manganese). E. Oxygen Residual
