【摘要】 复合糖类是自然界中广泛存在的物质,其共同特征是兼有糖类和其他非糖组分。糖苷是低分子质量的复合糖类。大分子质量的复合糖类主要是由糖类与蛋白质/肽、糖类与脂质组成。另一类复合糖类是磷酸二酯键连接的糖类,其主要代表是核酸。更多还原

【Abstract】 Complex carbohydrates occur widely in nature and their common feature is to contain both carbohydrate and non-carbohydrate moiety.Glycosides are complex carbohydrates having low molecular mass.The two types of conjugate,carbohy-drate with protein/pepetide and carboydrate with lipid,are larger complex carbohydrates.Another type of complex carbohy-drate possesses the backbone containing sugar linked by phosphate diester bond.Nucleic acid belongs to this type.更多还原
