This book describes the recent developments in enzymology in carbohydrate engineering based on modern sciences and technology, collected from recent symposia on agricultural biotechnology. It builds a bridge between basic knowledge and biotechnology in the field of carbohydrate chemistry and enzymology. The fundamental research and application of carbohydrate enzymes to agricultural biotechnology, concentrating on the structures and biochemical properties of various enzymes, and their production and application in plant and food is extensively described. This book will provide the reader with the most up-to-date information on development of enzymology in carbohydrate engineering.
