Polysaccharides from marine algae, differing from those of land plants, are known to exhibit many biological and physiological activities such as antioxidant activities, antithrombin-active, antitumor, antivirus, cell recognition and cell adhesion or regulation of receptor functions. Interest in the potential of seaweed polysaccharides as drugs is more increasing. The polysaccharides of interest in our laboratory include various polysaccharides from Phaeophyta and Rhodophyta. In the recent years, we are focusing on the polysaccharides from Chlorophyta. These polysaccharides from seaweeds are isolated and characterized. Chemical and enzymatic methods are used to break these polysaccharides into oligosaccharides, and the structural characteristic are studied by chemical methods and modern spectroscopic methods. The biological functions of low molecular weight polysaccharides with uncommon structures are investigated.
