A minimal presence of cobalt in soils therefore markedly improves the health of grazing animals, and an uptake of 0.20 mg/kg a day is recommended because they have no other source of vitamin B 12. [3] Proteins based on cobalamin use corrin to hold the cobalt. Coenzyme B 12 features a reactive C-Co bond that participates in the reactions. [4]
Cobalt: trace NE; NE: Cobalt is available for use by animals only after having been processed into complex molecules (e.g., vitamin B 12) by bacteria. Humans contain only milligrams of cobalt in these cofactors. A deficiency of cobalt leads to pernicious anemia. Animal muscle and liver are good dietary sources, also shellfish and crab meat. [35]
Trace metals are sometimes referred to as trace elements, although the latter includes minerals and is a broader category. See also Dietary mineral. Trace elements are required by the body for specific functions. Things such as vitamins, sports drinks, fresh fruits and vegetables are sources.
Protein is the key to keeping you full and energized. But when it comes to the source, some proteins stand above the rest, according to a new report from an advisory committee to the United States ...
Cobalt is a chemical element; it has symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, somewhat brittle, gray metal.
Micronutrients are essential dietary elements required in varying quantities throughout life to serve metabolic and physiological functions. [6] [7] Dietary minerals, such as potassium, sodium, and iron, are elements native to Earth, and cannot be synthesized. They are required in the diet in microgram or milligram amounts. As plants obtain ...
