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.

L-Seleno-L-methionine

CAS: 3211-76-5

L-Seleno-L-methionine is a selenium-containing amino acid that is found in the proteins of some plants and animals. It functions as an enzyme cofactor and aids in energy metabolism, protein synthesis, and other biochemical processes. Seleno-L-methionine has been shown to have a protective effect against oxidative damage by scavenging free radicals. It also increases mitochondrial membrane potential and prevents the release of proapoptotic factors from mitochondria into the cytosol. Seleno-L-methionine has been used for analytical purposes as well as to evaluate changes in cell signaling pathways due to chemiluminescence methods or chemical inhibitors. Seleno-L-methionine also has an antioxidant activity that reduces the production of reactive oxygen species (ROS) by reacting with hydroxyl radicals, hydrogen peroxide, nitric oxide, singlet oxygen, and peroxynitrite.
