Excessive molybdenum may kill you. Too few molybdenum will kill you. Have not you heard of molybdenum? You are not alone. This may be the most important element that no one knows.
Molybdenum containing 42 protons and 54 neutrons is in the middle of the periodic table and is completely ignored. This is useless. In fact, as an alloy to strengthen steel, it has great demand. I do not have sexy things that I can not decide. But if I tell you this is the only thing that prevents most of your food from killing you?
Molybdenum enters your diet through the plant and absorbs it from the soil. It forms an important part of a small enzyme called sulfite oxidase. The enzyme breaks down the incoming sulfite and turns it into a useful food. Taking molybdenum and enzymes makes things cumbersome. The lowest level problem you can expect is a serious allergic reaction. Continuous molybdenum deficiency causes urine to accumulate in the blood, causing severe inflammation and joint pain. In the worst case, molybdenum deficiency removes the nervous system
Can you avoid sulfite? This is possible. The US Food and Drug Administration (FDA) stipulates that it is illegal to add sulfite to raw fruits and vegetables, but almost all other foods contain sulfite. Fresh fruits, restaurants' cuisines (especially shells and potatoes), and almost everything on the grocery store shelves. Both beer and wine contain natural sulfite. Basically, as there is not enough molybdenum in your system, almost all food kills you.
Excessive molybdenum does the same thing. Sulfur is a criminal partner. The extra molybdenum in the system has a very high affinity for sulfur and it will combine with four sulfur atoms to form tetrathiomolybdate. Tetrathiomolybdate grabs nearby copper and can not be used for the body. You can chew and swallow the copper, and your system contains too much molybdenum, you still die due to copper deficiency
Molybdenum has a positive aspect. Scientists changed the danger to the gospel and found ways to use molybdenum to help rare people. It makes copper accumulation fatal.
Another interesting factor is the importance of molybdenum for mining and its exports. Molybdenum is a raw material for special steels and other alloys due to their special properties: high temperature and corrosion resistance, durability and strength (CODELCO, 2009). Despite political discussions on international price instability and diversification of exports and development of more value-added products, the importance of copper to Chile's exports and gross domestic product remains unchanged. In addition, some departments are seeking partial privatization of CODELCO, but there is no agreement on this yet.
Molybdenum is the 54th abundant element in the Earth 's crust, the 25th abundant element in the ocean, an average of 1 / 1,000,000, the 42nd most abundant element in the universe. The Russian Luna 24 mission found a pyroxene piece containing molybdenum particles (1 x 0.6 μm) taken from Mare Crisium on the moon. The relative rarity of molybdenum in the crust is often offset and often found by its concentration in many water insoluble ores combined with sulfur as copper. Molybdenum is contained in minerals such as ulpenite (PbMoO 4) and paolite (CaMoO 4), but the main commercial source is molybdenum (MoS 2). Molybdenum is mined as a major ore and recycled as a byproduct of copper and tungsten mining.
