Molybdenum is a transition metal, which may act as a catalyst for one- and twoelectron redox reactions, due to its physicochemical properties. Molybdatesbecame part of metalloenzymes early in evolution and may be still found in the majority of organisms, except some anaerobes where tungsten is present instead of molybdenum. In mammals three molybdoenzymes are found and xanthine oxidase which catalyses the oxidation of purines to uric acid and theoxidation of other heterocycles is best known. The other enzyme sulfite oxidase is essential for living as it catalyses the metabolism of sulfur containing organic compounds and prevents the accumulation of toxic sulfites in the organism. In humans there is only one case of molybdenum deficiency presented in professional literature, therefore the use of additives containing molybdenum has no rational base. Also the cases of poisoning with the ingested molybdenum compounds have not been clearly described.
