CAS 3211-76-5: L-Selenometionina
Descripción:
L-Selenometionina es un compuesto de organoselenio que sirve como un aminoácido que ocurre de forma natural y como un análogo de selenio de la metionina. Se caracteriza por la presencia de un átomo de selenio en lugar del átomo de azufre que se encuentra en la metionina, lo que contribuye a sus propiedades bioquímicas únicas. Este compuesto es conocido por su papel en el metabolismo del selenio y a menudo se estudia por sus potenciales propiedades antioxidantes y beneficios para la salud, particularmente en relación con la prevención del cáncer y la función inmunológica. L-Selenometionina se encuentra típicamente en varios alimentos, especialmente en nueces de Brasil, y también puede ser sintetizado para su uso en suplementos dietéticos. Es soluble en agua y exhibe estabilidad en condiciones normales, aunque puede ser sensible a niveles extremos de pH y altas temperaturas. El compuesto es reconocido por su capacidad para incorporar selenio en proteínas, influyendo así en varios procesos biológicos. Su perfil de seguridad es generalmente favorable, pero como cualquier suplemento, debe ser consumido dentro de las pautas recomendadas para evitar la toxicidad potencial asociada con la ingesta excesiva de selenio.

CAS: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.
