Metallothionein (MT) is a family of cysteine -rich, low molecular weight (MW ranging from 500 to 14000 Da) proteins. They are localized to the membrane of the Golgi apparatus. MTs have the capacity to bind both physiological (such as zinc, copper, selenium) and xenobiotic (such as cadmium, mercury, silver, arsenic, lead) heavy metals through ...
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 ...
Copper [5] Chlorine. Selenium. Manganese. Molybdenum. Cobalt (as a component of vitamin B 12) Fluorine. Iodine [6] Silicon [7]
Micronutrient. Micronutrients are essential dietary elements required by organisms in varying quantities to regulate physiological functions of cells and organs. [1][2] Micronutrients support the health of organisms throughout life. [3][4][5] In varying amounts supplied through the diet, micronutrients include such compounds as vitamins and ...
Molybdenum is an essential element in most organisms; a 2008 research paper speculated that a scarcity of molybdenum in the Earth's early oceans may have strongly influenced the evolution of eukaryotic life (which includes all plants and animals). [82] At least 50 molybdenum-containing enzymes have been identified, mostly in bacteria.
Selenium is a component of the amino acids selenocysteine and selenomethionine. In humans, selenium is a trace element nutrient that functions as cofactor for glutathione peroxidases and certain forms of thioredoxin reductase. [1] Selenium-containing proteins are produced from inorganic selenium via the intermediacy of selenophosphate (PSeO 3 3 ...
Chromium deficiency is described as the consequence of an insufficient dietary intake of the mineral chromium. Chromium was first proposed as an essential element for normal glucose metabolism in 1959, [1] but its biological function has not been identified. [2] Cases of deficiency were described in people who received all of their nutrition ...
Mineral deficiency. Specialty. Endocrinology. Mineral deficiency is a lack of the dietary minerals, the micronutrients that are needed for an organism's proper health. [1] The cause may be a poor diet, impaired uptake of the minerals that are consumed, or a dysfunction in the organism's use of the mineral after it is absorbed.
