What is Selenomethionine Powder?
Selenomethionine Powder has different configurations. The physiological activity and bioavailability of selenoamino acids with different configurations vary greatly. Generally speaking, only L-selenoamino acids can be absorbed and utilized by living tissues, while D-selenoamino acids or racemic selenoamino acids may cause greater harm to the human body. Selenomethionine prepared by conventional chemical synthesis is generally DL-racemic compound. If it is to be used as a food, feed additive and medicine, it must be optically pure L-selenomethionine.
Selenium (Se) is an essential trace element for the human body. Selenium deficiency can cause physiological dysfunction in the human body and lead to diseases such as Keshan disease. Some selenium-containing enzymes in the human body can remove peroxides and prevent cell damage. Selenium is also an antioxidant with a strong antagonistic effect on heavy metals. Therefore, the pharmacological, biological and biochemical properties of selenium have aroused people's interest, and the development of selenium-containing drugs has become a research hotspot. DL-selenomethionine, as a natural organic selenide in living organisms, is gradually replacing traditional inorganic substances such as sodium selenite as a source of selenium supplementation. At the same time, as an intermediate for other selenium-containing drugs, it has gradually become the focus of the development of selenium-containing compounds.
There are mainly two preparation methods:
(1) a-aminobutyrolactone hydrochloride and sodium methylselenol addition ring opening method: a-aminobutyrolactone hydrochloride and sodium methylselenol addition ring opening are used, and the preparation of sodium methylselenol requires toxic and smelly dimethyl diselenide as a raw material, which is difficult to produce on a large scale.
(2) Homocystine method: a-amino-protected homoserine lactone is reacted with metal diselenide to generate a-amino-protected diselenogeno-homocystine, which is then reduced and deprotected to obtain selenomethionine. Although this method avoids the use of highly toxic and smelly dimethyl diselenide, the operation steps are cumbersome. Our extensive research found that each step-by-step treatment process has a foul and toxic smell, and the expensive, volatile, and highly toxic iodomethane is used as the alkylation agent in the alkylation step, resulting in the product being too dark in color and difficult to purify.
Application
DL-selenomethionine, as a natural organic selenium source in living organisms, is gradually replacing inorganic compounds such as sodium selenite and becoming a good source of selenium supplementation. It is also an intermediate for the preparation of other selenium-containing drugs and has become the development focus of selenium compounds.
DL-selenomethionine is a selenium-containing amino acid in which the S in methionine is replaced by Se. It plays an important role in maintaining the physiological functions of the human body and preventing and treating certain diseases. The application of DL-selenomethionine and its innovative compounds in various fields of life sciences is becoming increasingly extensive and in-depth, especially in the prevention and treatment of diabetes, which is a hot topic of concern at home and abroad. Studies have found that DL-selenomethionine is one of the forms of organic selenium in artificially produced selenium-rich natural foods. The production of these selenium-rich natural foods is often limited by conditions, while the use of chemical methods to synthesize selenomethionine is not limited by natural conditions and is an effective way to produce selenium supplement products. DL-selenomethionine has unique biological effects such as high antioxidant capacity, low toxicity, and high absorption and utilization rate, and has efficacy unmatched by other organic selenium compounds. It is widely used in food, beverages, health products, and in the treatment of gastrointestinal diseases, diabetes, and Alzheimer's disease drugs.
