生物大分子结构与功能的研究是生物化学和分子生物学的一个核心内容,糖类的研究重新获得了人们的青睐,成为生命科学研究中继蛋白质、核酸后的下一个重要探索目标。十九世纪确定了碳水化合物的环状结构、立体构型和光学性质后,生物学家长期认为它除了提供能量维持生命外,只有结构组织的功能。五十年代蛋白质氨基酸组成的研究及后来的核酸高潮推动了生物化学和分子生物学的发展,七十年代免疫学的进展,认为抗体是一种含有共 The study on the structure and function of biological macromolecule is a core part of biochemistry and molecular biology. The researches on carbohydrates have regained the favor of people and become the next important exploration target after the relay of proteins and nucleic acids in life science research. After the nineteenth century identified the cyclic structure, stereostructure and optical properties of carbohydrates, biologists have long believed that apart from providing energy to sustain life, only the function of structural organization. Fifties protein amino acid composition and subsequent nucleic acid climax to promote the development of biochemistry and molecular biology, the progress of immunology in the seventies, that antibody is a containing
