Outline and Purpose of the Course	Distribution and interrelationships of the main components, namely, cellulose, hemicellulose and lignin, are important information for effective utilization of woody biomass abundantly present on the earth. In this lecture, recent discoveries on the detection method and formation process of each component and the molecular construction of the cell wall are introduced.
Course Goals	・ Understanding in the principle and problems of detection method of major cell wall components of timbers. ・ Understanding in the formation process of major cell wall components of timbers. ・ Understanding in the interrelationship of each component on timber cell walls.
Schedule and Contents	Lectures of 1 to 2 weeks per subject is planned for the following subjects. 1. Method for detection of cellulose In the cell wall of woody biomass, cellulose forms a structure called microfibril. A microscopic visualization method of cellulose microfibrils and a detection method of cellulose are discussed. 2. Detection of hemicellulose Many types of monoclonal antibodies have been developed for hemicellulose. These types and their possibilities are discussed. 3. Distribution and deposition process of hemicellulose With the development of specific antibodies, new findings on hemicellulose deposition processes are being obtained. These research examples are introduced. 4. Detection method of lignin distribution As to lignin distribution, various detection methods have been used in connection with the pulping method. The detection method of lignin having a complicated structure compared to hemicellulose are explained. 5. Distribution and Deposition Process of Lignin Studies on cell wall formation and lignification process in coniferous wood and hardwood materials are introduced and the future developments are explained.
