Abstract
Natural polysaccharide is one of three major classes of biological macromolecules. Cellulose, starch, and chitin are the most abundant polysaccharides and have been used in various application fields. Therefore, the precision chemical synthesis of related polysaccharides as well as non-natural polysaccharides is a promising research topic to provide new functional environmentally benign materials in biomedical and tissue engineering applications.However, the diverse structures of polysaccharides have caused the difficulty in their chemical synthesis with well-defined structures. Beyond such problem, recently, facile methods for the precision synthesis of polysaccharides are developed such as the approach by enzymatic reactions. Furthermore, polysaccharides have been found to show self-assembling properties, which employed to construct supramolecular materials. Much of the present speech will concern with the speaker’s own works in these research area
