Selenomethionine

Description:

Selenomethionine is an organoselenium compound characterized by the presence of selenium in place of sulfur in the amino acid methionine. It is a naturally occurring amino acid and is classified as a non-proteinogenic amino acid, meaning it is not incorporated into proteins during translation. Selenomethionine is notable for its antioxidant properties, as it can help mitigate oxidative stress in biological systems. It is often found in various foods, particularly in Brazil nuts, and is also available as a dietary supplement due to its potential health benefits, including supporting immune function and thyroid health. The compound is soluble in water and exhibits a relatively stable structure under physiological conditions. Its chemical formula is C5H11N1O2Se, and it has a molecular weight that reflects the presence of selenium. Selenomethionine is of interest in research for its role in selenium metabolism and its potential therapeutic applications, particularly in cancer prevention and treatment. However, excessive intake can lead to toxicity, highlighting the importance of balanced consumption.
