Manganum (MN, Manganum)

History manganese

The reproductors of the manganese is considered to be Swedish chemists K. Shelele and Y. Ghana, the first of which in 1774 found an unknown metal in a widely used iron ore called in antiquity black magnesiathe second way of heating the mixture of pyrolyzit (main mineral manganese) with the coal received a metal manganese (Calorizator). Name New metal received from German Manganerz.. Manganese ore.

Manganese is an element of a side subgroup of VII group IV periodic system of chemical elements D.I. Mendeleev has atomic number 25 and atomic mass 54,9380. Accepted designation - MN. (from Latin Manganum).

Finding in nature

Manganese is quite common, it enters the second ten elements in prevalence. In the earth's crust, it is most often found together with iron ores, but there are precisely manganese deposits, for example in Georgia and Russia.

Manganese is a heavy silver-white metal, the so-called blackmetal. When heated, it has an influence of water, displacing hydrogen. In the usual condition absorbs hydrogen.

Daily need for manganese

For an adult healthy person, the daily need for manganese is 5-10 mg.

The manganese enters the human body with food, so it is mandatory to eat one or more products from the following list every day:

• nuts (,)
• cereals and cereals (, wheat)
• legumes (,)
• vegetables and greens ()
• berries and fruits (,)
• mushrooms (,)

Useful properties of manganese and its influence on the body

Functions of manganese in the human body:

• regulation of blood glucose level, stimulation of production
• prevention of diabetes sugar by reducing blood sugar levels
• normalization of brain activity and processes in the nervous system
• participation in the work of the pancreas and synthesis of cholesterol
• promotion of the growth of connective tissues, cartilage and bones
• impact on lipid exchange and preventing excessive fat in the liver
• participation in cell division
• reducing the activity of "bad" cholesterol and slowdown in the growth of cholesterol plaques.

Interaction with others

Manganese helps to intensify the enzymes necessary for the right use by the body, and. The interaction of manganese C and is a recognized antioxidant means. Large doses and will delay the suction of manganese.

Marganese has found the greatest use in metallurgy, also in the production of risostats, electroplating elements. Manganese compounds are used as thermoelectric material.

Signs of lack of manganese

In the power of the power, driving a large amount of carbohydrates, a manganese overruns in the body, which is manifested by the following symptoms: anemia, reduced bone strength, growth delay, and ovarian atrophy in women and testicles in men.

Signs of excess manganese

Excess manganese is also uncomfortable by the body, his manifestations can serve drowsiness, pain in the muscles, loss of appetite and changes in the formation of bones - the so-called "manganese" Rakhit.
