CAS 3211-76-5: L-Selenomethionine

Description:L-Selenomethionine is an organoselenium compound that serves as a naturally occurring amino acid and a selenium analog of methionine. It is characterized by the presence of a selenium atom in place of the sulfur atom found in methionine, which contributes to its unique biochemical properties. This compound is known for its role in selenium metabolism and is often studied for its potential antioxidant properties and health benefits, particularly in relation to cancer prevention and immune function. L-Selenomethionine is typically found in various foods, especially in Brazil nuts, and can also be synthesized for use in dietary supplements. It is soluble in water and exhibits stability under normal conditions, although it can be sensitive to extreme pH levels and high temperatures. The compound is recognized for its ability to incorporate selenium into proteins, thereby influencing various biological processes. Its safety profile is generally favorable, but like any supplement, it should be consumed within recommended guidelines to avoid potential toxicity associated with excessive selenium intake.
