The Physiological Effect and Molecular Modification of Algae Polysaccharides

The polysaccharides obtained from a species of algae have proved to be a potent clinical agent.The latest research about physiological effect of algae polysaccharides in antivirus,antitumor,immunological activation and immunosuppress was synopsis introduced,emphasizing to introduce the studies of different physiological mechanisms of different generic algae polysaccharides.The structure\|effect relationships between algae polysaccharides and physiological effect were also mentioned.Many research results indicated that chemical modification of the polysaccharide was necessary to improve the modulation binding specificity and activity toward its biological targets.Modification of algae polysaccharides is an effective way to enhance the polysaccharides positive effect and reduce side effect.The different algae polysaccharides modification methods were enumerated and the improvement of modified polysaccharides was evaluated.
