also acts as a cofactor that is required for the of sulfur-containing amino acids, nitrogen-containing compounds found in DNA and RNA, and various other functions. Deficiency of molybdenum is not seen in healthy people, however, a rare metabolic effect called molybdenum cofactor deficiency is the result of an insufficient amount of molybdoenzymes in the body. Due to rapid excretion rates in the urine of the mineral, molybdenum toxicity is low in humans.
