Selenomethionine

Description:
Selenomethionine is an organoselenium compound characterized by the presence of selenium in place of sulfur in the amino acid methionine. It is classified as a non-proteinogenic amino acid and is notable for its role as a dietary supplement and potential antioxidant. Selenomethionine is recognized for its ability to incorporate selenium into proteins, which is essential for various biological functions, including antioxidant defense and thyroid hormone metabolism. The compound is generally stable under normal conditions but can be sensitive to extreme pH levels and high temperatures. It is soluble in water and exhibits a relatively low toxicity profile, making it suitable for use in nutritional supplements. Selenomethionine is also studied for its potential health benefits, including immune support and cancer prevention, although further research is needed to fully understand its mechanisms and efficacy. Its CAS number, 2578-28-1, is used for identification in chemical databases and regulatory contexts.
