学过基础有机化学的人都知道,直链淀粉和纤维素都是D—(+)—吡喃葡萄糖的多糖,不过,直链淀粉是α—葡萄糖通过α—1,4甙链相连接而成的长链,而纤维素是β—葡萄糖通过β—1,4甙相连接而成的长链。这就是说,直链淀粉和纤维素的一级结构相差甚微。然而大家知道,直链淀粉和纤维素的高级结构相差悬殊,纤维素的直链会形成纤维结构而直链淀 Anyone who has learned basic organic chemistry knows that both amylose and cellulose are D - (+) - glucopyranose polysaccharides, however, amylose is the alpha-glucose linked by alpha-1,4 glucosidic linkages Into long chains, while cellulose is a long chain of β-glucose linked by β-1,4 glycosides. This means that there is little difference between the primary structure of amylose and cellulose. However, as we all know, there is a great difference between the higher structures of amylose and cellulose. The straight chain of cellulose will form a fibrous structure and the amylose
