Molybdenum
Molybdenum (pronounced /məˈlɪbdɪnəm/) is a chemical element with the symbol Mo and atomic number 42.
Etymology
The word Molybdenum is derived from the Greek word molybdos, meaning lead. It was named by Swedish chemist Carl Wilhelm Scheele, who identified it as a distinct element in 1778.
Description
Molybdenum is a silvery-white, hard, transition metal. It has one of the highest melting points of all pure elements, and it is used in various applications that require high-strength materials that can withstand high temperatures and pressures.
Medical Significance
In the medical field, Molybdenum is an essential trace element in the human body. It is found in several enzymes, including xanthine oxidase, aldehyde oxidase, and sulfite oxidase. These enzymes play a crucial role in the metabolism of purines and pyrimidines, which are building blocks of DNA and RNA.
Molybdenum deficiency is rare but can lead to metabolic disturbances. On the other hand, excessive intake of Molybdenum can cause gout-like symptoms.
