Selenium

Journal of Toxicology: Clinical Toxicology, 1999
The 4 natural oxidation states of selenium are elemental selenium (0), selenide (-2), selenite (+4), and selenate (+6). Inorganic selenate and selenite predominate in water whereas organic selenium compounds (selenomethionine, selenocysteine) are the major selenium species in cereal and in vegetables.

Selenium and nano-selenium in agroecosystems

Environmental Chemistry Letters, 2014
Selenium (Se) is an essential health element becoming rare in food as a result of intensive plant pro- duction. Indeed, several enzymes contain selenium in the form of the unusual selenocysteine amino acid. Selenium was found an essential nutrient in the late 1950s, when selenium was found to replace vitamin E in the diets of rats and chicks for the ...

Selenium in Uremia

Artificial Organs, 1995
Abstract: The importance of selenium as an essential trace element for man has been increasingly recognized during the last several years. Selenium deficiency has been associated with cases of congestive cardiomyopa‐thy, skeletal myopathy, anemia, enhanced cancer risk, elevated incidence of cardiovascular disease, immune system alterations, hair and ...

Mobilization of selenium by a selenium-dependent bacterium

Biological Trace Element Research, 1990
A selenium-dependent bacterium, Bacillus sp., failed to grow on selenium-free media. However, it is able to grow at high concentrations of sodium selenite containing media up to 3% (w/v). It accumulated extraordinary high quantities of selenium, 432 ppm/mL.

Metabolism of selenium in a selenium-dependent bacterium

Biological Trace Element Research, 1990
A selenium-dependent Bacillus sp. is able to grow well up to 3% sodium selenite-containing media. The bacterium completely failed to grow on media devoid of selenium. The presence of selenium in the growth media increased the bacterial contents of proteins, carbohydrates, and lipids.

Selenium

2015
Selenium occurs as inorganic selenite or selenate and in organic forms in plants and other organisms used for food. The human selenoproteome consists of 25 selenoproteins. The main groups are glutathione peroxidases 1-5, iodothyronine deiodinases 1-3, thioredoxin reductases, selenoprotein P (SelP), and other proteins mostly with unknown function.
