| Abstract: | Polysaccharides have received much attention with respect to their biological functions such as immuactivity, anti-tumor and antioxidant. On the basis of analysis on the references about polysaccharides, this paper summarized the effect of molecule side chain, molecular weight, molecular modified, solution, metal ion, temperature, pH and ultrahigh pressure on conformation, analyzed the relationship of flexibility helix form of molecule chain to bioactivity, and proposed the scientific problems and the development tendency of relationship of polysaccharide molecular chain comformation changes and bioactivities. |
