Abstract

It is thought that wood components are produced by a tree for its survival, and have suitable chemical structures for the purpose. Then, the elucidation of relationship between chemical structures and their properties is one of the important approaches for new effective utilization of wood components. In this manuscript, fundamental explanation for chemical structures of wood components and recent studies of wood components in our laboratory are mentioned.<BR>Wood consists of main component (cellulose, hemicellulose, lignin) and minor component (extractives). Cellulose has a suitable chemical structure for crystallization (linear polymer with strictly regular structures), and is a construction material of cell walls. Hemicellulose has a suitable chemical structure as an amorphous material, and contributes to the formation of 3D structures of cell walls. Lignin is an aromatic polymer, and plays important roles for the formation of vascular bundle in a tree. Extractives are the important components for controlling the characteristic properties of each tree. As our recent studies, novel cellulose derivatives for photo-current generation system and new analysis method for Lignin-Carbohydrate Complex (LCC) and are also described.
