Molybdenum is an element with atomic symbol Mo, atomic number 42, and atomic weight 95.94.
Molybdenum is a transition element and is present in several human enzymes, such as xanthine and sulfite oxidases, and in enzyme cofactors in oxidative reduction reactions.
Molybdenum is found in many foods and deficiencies are rare. Molybdenum deficiency has been described in animals and rare cases have been reported in patients on total parenteral nutrition, clinical signs being mental disturbances and coma accompanied by hypouricemia and hypermethioninemia.
Molybdenum is relatively nontoxic, although high levels may be a cause of high.
Oxygen is the chemical element with the symbol O and atomic number 8, meaning its nucleus has 8 protons.
Oxygen is a member of the chalcogen group on the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.
Dioxygen is used in cellular respiration and many major classes of organic molecules in living organisms contain oxygen, such as proteins, nucleic acids, carbohydrates, and fats, as do the major constituent inorganic compounds of animal shells, teeth, and bone.
Oxygen was isolated by Michael Sendivogius before 1604, but it is commonly believed that the element was discovered independently by Carl Wilhelm Scheele, in Uppsala, in 1773 or earlier, and Joseph Priestley in Wiltshire, in 1774.
