WebChemical modification is the most widely used method; it can significantly increase the water solubility and bioactivities of polysaccharides by grafting onto other groups. Physical and biological modifications only change the molecular weight of a polysaccharide, and thereby change its physicochemical properties and bioactivities. WebIn recent years, studies have shown that structural modification of polysaccharides can improve the immunological activity of polysaccharides. The common chemical modifications are sulfation, carboxymethylation, acetylation, phosphorylation, and so on. The chemical modification of polysaccharides and the immunomodulation of …
