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 ...
Selenomethionine is a selenide-containing amino acid that also occurs naturally, but is generated by post-transcriptional modification. Organoselenium chemistry in organic synthesis [ edit ]
For example, selenomethionine and selenocysteine are selenium-containing amino acids present in the human body. Selenomethionine participates in the synthesis of selenoproteins . [ 2 ] The reduction potential and pKa (5.47) of selenocysteine are lower than those of cysteine , making some proteins have antioxidant activity. [ 3 ]
Selenium is a component of the unusual amino acids selenocysteine and selenomethionine. In humans, selenium is a trace element nutrient that functions as cofactor for reduction of antioxidant enzymes, such as glutathione peroxidases and certain forms of thioredoxin reductase found in animals and some plants (this enzyme occurs in all living ...
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 ...

Methaneselenol (commonly named "methylselenol") (CH 3 SeH), which can be produced in vitro by incubating selenomethionine with a bacterial methionine gamma-lyase (METase) enzyme, by biological methylation of selenide ion or in vivo by reduction of methaneseleninic acid (CH 3 −Se(=O)−OH), has been invoked to explain the anticancer activity ...
