This metal is considered essential because it is part of a complex called molybdenum cofactor that is required for the three mammalian enzymes xanthine oxidase (XO), aldehyde oxidase (AO), and sulfite oxidase (SO). XO participates in the metabolism of purines, AO catalyzes the conversion of aldehydes to acids, and SO is involved in the metabolism of sulfur\u2010containing amino acids. Molybdenum deficiency is not found in free\u2010living humans, but deficiency is reported in a patient receiving prolonged total parenteral nutrition with clinical signs characterized by tachycardia, headache, mental disturbances, and coma. The biochemical abnormalities in this acquired molybdenum deficiency include very low levels of uric acid in serum and urine (low XO activity) and low inorganic sulfate levels in urine (low SO activity). Inborn errors of isolated deficiencies of XO, SO, and molybdenum cofactor are described. Although XO deficiency is relatively benign, patients with isolated deficiencies of SO or molybdenum cofactor exhibit mental retardation, neurologic problems, and ocular lens dislocation. These abnormalities seem to be caused by the toxicity of sulfite and\/or inadequate amounts of inorganic sulfate available for the formation of sulfated compounds present in the brain. XO and AO may also participate in the inactivation of some toxic substances, inasmuch as studies suggest that molybdenum deficiency is a factor in the higher incidence of esophageal cancer in populations consuming food grown in molybdenum\u2010poor soil.<\/jats:p>","DOI":"10.1177\/0115426593008006277","type":"journal-article","created":{"date-parts":[[2008,5,14]],"date-time":"2008-05-14T19:23:41Z","timestamp":1210793021000},"page":"277-281","source":"Crossref","is-referenced-by-count":70,"title":["Molybdenum: An Essential Trace Element"],"prefix":"10.1002","volume":"8","author":[{"given":"Vishwanath M.","family":"Sardesai","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[1993,12]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/141553a0"},{"key":"e_1_2_1_3_1","doi-asserted-by":"crossref","first-page":"96","DOI":"10.1093\/jn\/111.1.96","article-title":"Influence of dietary molybdenum on copper metabolism in ponies","volume":"111","author":"Cymbalark NF","year":"1981","journal-title":"J Nutr"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.109.2821.68"},{"key":"e_1_2_1_5_1","doi-asserted-by":"crossref","first-page":"915","DOI":"10.1016\/S0021-9258(19)52361-4","article-title":"Isolation and identification of the xanthine oxidase factor as molybdenum","volume":"203","author":"Richert DA","year":"1953","journal-title":"J Biol Chem"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-9861(53)80001-9"},{"key":"e_1_2_1_7_1","first-page":"465","article-title":"Studies on metallo\u2010flavoproteins.
