Molybdenum is an essential trace mineral necessary for the functioning of the enzyme xanthine oxidase. This enzyme is involved in the metabolism and utilization of iron and the production of uric acid(for excretion in the urine) from the breakdown of amino acids. Most of our molybdenum is stored in the liver, where the majority of its enzyme reactions take place.
