Selenium in biology. Selenocysteine is the main organic molecule involving selenium in humans. Selenium is an essential micronutrient for animals, though it is toxic in large doses. In plants, it sometimes occurs in toxic amounts as forage, e.g. locoweed. Selenium is a component of the amino acids selenocysteine and selenomethionine.
Snails are a good source of selenium. Of the recommended daily requirement of selenium, the snail provides up to 50% (in women) and 30% (in men). Snail flesh is a good supply of essential amino acids such as lysine, methionine, and cysteine, which are difficult to get in other sources of protein, according to Adeyeye et al. (2020).
: 151 As an example of the importance of seasonal food on maintaining balance of the humours and preventing disease is given by Hippocrates in "On Regimen" when the authors state that, "in winter, to secure a dry and hot body it is better to eat wheaten bread, roast meat, and few vegetables; whereas in summer it is appropriate to eat barley ...
Selenium is a chemical element; it has the symbol Se and atomic number 34. It is a nonmetal (more rarely considered a metalloid) with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium, and also has similarities to arsenic. [9] It seldom occurs in its elemental state or as pure ore ...
Selenium yeast. Selenium yeast is a feed additive for livestock, used to increase the selenium content in their fodder. It is a form of selenium currently approved for human consumption in the EU and Britain. [1] Inorganic forms of selenium are used in feeds (namely sodium selenate and sodium selenite, which appear to work in roughly the same ...

In addition to calcium, it is important in the regulation of neuromuscular activity. Food sources include bananas, avocados, nuts, vegetables, potatoes, legumes, fish, and mushrooms. Sodium, a common food ingredient and electrolyte, found in most foods and manufactured consumer products, typically as sodium chloride (salt).
Selenomethionine (SeMet) is a naturally occurring amino acid. The L -selenomethionine enantiomer is the main form of selenium found in Brazil nuts, cereal grains, soybeans, and grassland legumes, while Se -methylselenocysteine, or its γ-glutamyl derivative, is the major form of selenium found in Astragalus, Allium, and Brassica species.
