Methodogy of Study on Conformation of Polysaccharide

Polysaccharides play multiple roles and have extensive bioactivities in life process.Bioactivities of polysaccharides have a close relation to their chain conformation.The major research methods of polysaccharide conformation(Congo red experiment,circular dichroism spectrum,viscosity method,light scattering method,size exclusion chromatography,atomic force microscope),corresponding procedures,and the external factors affecting polysaccharide conformation were reviewed.
