The principle of action of yeast cell wall polysaccharides

β - glucan is a polysaccharide with a special structure. Unlike other sugars, the monosaccharides of sugars are generally bound by β -1,4 bonds, while the monosaccharides in β - glucan are connected by β -1,3 and β -1,6 bonds. Its unique ultrafine spiral molecular structure can be the most immunologically active and easily absorbed form. Its unique configuration is easily accepted by the immune system. Most animals have a large number of macrophages in their reticuloendothelial system. Generally, macrophages are not active. When β - glucan binds to macrophages through LECTIN (a special protein on the surface of macrophages), macrophages are activated and can induce a series of cellular and humoral immune responses in the body, thereby improving the body's immune function. Therefore, β - glucan is also known as an immunopolysaccharide. In recent years, research has shown that β - glucan can enhance the activity of lysozyme, increase the activity of immune related enzymes, and activate B and T cells.
Mannose oligosaccharides (MOS) are composed of 2-10 monosaccharides, with α -1,2 between the monosaccharides; The alpha-1,3 and alpha-1,6 bonds are connected, with the main chain being joined by alpha-1,6 bonds and the side chains being joined by alpha-1,2 and alpha-1,3 bonds. They are mostly alkaline soluble. It can identify, adhere, and eliminate pathogenic microorganisms, and provide beneficial health benefits to the host by regulating the microbiota structure in the animal digestive tract.
