Endocrinology. Molybdenum deficiency refers to the clinical consequences of inadequate intake of molybdenum in the diet. The amount of molybdenum required is relatively small, and molybdenum deficiency usually does not occur in natural settings. [1] However, it can occur in individuals receiving parenteral nutrition. [2][3]
Although human toxicity data is unavailable, animal studies have shown that chronic ingestion of more than 10 mg/day of molybdenum can cause diarrhea, growth retardation, infertility, low birth weight, and gout; it can also affect the lungs, kidneys, and liver. [98] [99] Sodium tungstate is a competitive inhibitor of molybdenum. Dietary ...
Molybdenum cofactor deficiency is a rare human disease in which the absence of molybdopterin – and consequently its molybdenum complex, commonly called molybdenum cofactor – leads to accumulation of toxic levels of sulphite and neurological damage. Usually this leads to death within months of birth, due to the lack of active sulfite oxidase.
The river water was contaminated with toxic metals including arsenic, copper, barium, cadmium, chromium, lead, mercury, nickel, and thallium. [ 2 ] Cleanup costs may exceed $1.2 billion. [ 3 ] A toxic heavy metal is a common but misleading term for a metal noted for its potential toxicity. [ 4 ] Not all heavy metals are toxic and some toxic ...
Metal allergies inflame the skin after it has been in contact with metal. They are a form of allergic contact dermatitis. They are becoming more common, as of 2021, except in areas with regulatory countermeasures. People may become sensitized to certain metals by skin contact, usually by wearing or holding consumer products (including non-metal ...
Ammonium tetrathiomolybdate is the chemical compound with the formula (NH 4) 2 MoS 4. This bright red ammonium salt is an important reagent in the chemistry of molybdenum and has been used as a building block in bioinorganic chemistry. The thiometallate (see metallate) anion has the distinctive property of undergoing oxidation at the sulfur ...

Mineral (nutrient) Carbonic anhydrase, an enzyme that requires zinc (gray sphere near the center of this image), is essential for exhalation of carbon dioxide. In the context of nutrition, a mineral is a chemical element. Some "minerals" are essential for life, but most are not. [1][2][3] Minerals are one of the four groups of essential ...
