Manganese superoxide dismutase (MnSOD) is the principal antioxidant in mitochondria. Several enzymes activated by manganese contribute to the metabolism of carbohydrates, amino acids, and cholesterol. [2] A deficiency of manganese causes skeletal deformation in animals and inhibits the production of collagen in wound healing. [3]
Manganese deficiency in humans, which is rare, results in a number of medical problems. Many common vitamin and mineral supplement products fail to include manganese in their compositions. Relatively high dietary intake of other minerals such as iron, magnesium, and calcium may inhibit the proper intake of manganese.
Manganese oxide is used as an oxidising agent; as a rubber additive; and in glass making, fertilisers, and ceramics. Manganese sulfate can be used as a fungicide. Manganese is also an essential human dietary element, important in macronutrient metabolism, bone formation, and free radical defense systems.
[59] [60] Manganese(II) ions are often used as a contrast agent in animal studies, often called MEMRI (manganese-enhanced MRI). [61] Because Mn 2+ ions can enter cells through calcium transport channels, it has been used for functional brain imaging. [62] Manganese(III) chelates with porphyrins and phthalocyanines have also been studied. [57]
Magnesium sulfate as a medication is used to treat and prevent low blood magnesium and seizures in women with eclampsia. [1] It is also used in the treatment of torsades de pointes, severe asthma exacerbations, constipation, and barium poisoning. [1] [2] It is given by injection into a vein or muscle as well as by mouth.
The manganese pyridiniumyl derivative has shown the highest photodynamic activity, while the nickel analogue is photoinactive. [ 3 ] Another metallo-porphyrin complex, the iron chelate, is more photoactive (towards HIV and simian immunodeficiency virus in MT-4 cells) than the manganese complexes; the zinc derivative is photoinactive.
Organomanganese chemistry is the chemistry of organometallic compounds containing a carbon to manganese chemical bond.In a 2009 review, Cahiez et al. argued that as manganese is cheap and benign (only iron performs better in these aspects), organomanganese compounds have potential as chemical reagents, although currently they are not widely used as such despite extensive research.
Mustard seeds contain manganese, iron, and magnesium, all chemicals that have anti-inflammatory properties, evidence of using mustard as a way to treat inflammation dates back to Ancient Greece where it is said that Pythagoras recommended mustard seeds as a remedy for scorpion stings.
