China Supply CAS 3211-76-5 L-Selenomethionine Powder with Best Price

L-SelenoMethionine is the L-isomer of Selenomethionine, the main natural food form of selenium. L-SelenoMethionine is a cancer chemopreventive agent that can reduce the incidence of cancer and induce apoptosis of cancer cells through dietary supplementation. L-SelenoMethionine can also increase the expression of glutathione peroxidase.

L-Selenomethionine is a white to off-white solid powder at room temperature and normal pressure.
It is a selenium analogue of methionine and is found in plants such as cabbage and garlic, as well as in some microorganisms in nature.
As a chiral amino acid, it shares the common physicochemical properties of amino acids, such as being capable of undergoing a color reaction with indole-2,3-dione. However, due to the presence of selenium, it is more sensitive to oxidants.
Main application fields
‌Nutrition supplementation and feed additives‌: L-selenomethionine is regarded as a safe, effective and highly bioavailable form of selenium supplementation.‌
In the feed industry, zinc-L-selenomethionine preparations have been approved by the European Union as feed additives for all animals, and have also been approved by the United States for use in broiler feed.‌
It is often used as a nutritional supplement of selenium. Selenium, as an essential trace element for the human body, is a cofactor of glutathione peroxidase and plays a crucial role in antioxidant functions.‌
Biomedical Research and Disease Prevention: L-selenomethionine is an important target for "human endogenous metabolite" research.
Studies have shown that it may have a chemical prevention effect on prostate cancer and other diseases, and can reduce the incidence of cancer and induce apoptosis of cancer cells through dietary supplementation.
It can act as an antioxidant and has cytotoxicity against various types of cancer cells such as lung cancer, breast cancer, and colorectal cancer.
Furthermore, in Alzheimer's disease model mice, it was found to promote hippocampal neurogenesis through specific pathways.
It is also believed to enhance sperm vitality, improve the body's antioxidant capacity and immunity, and help eliminate toxins (such as heavy metals) from the body.
Other field expansion: By chemically modifying L-selenomethionine (such as synthesizing N-acyl derivatives), its application potential in food, medicine, cosmetics, etc. can be expanded.
