多糖

纤维素的球棍模型图
直链淀粉是葡萄糖的直链聚合物,主要以α键(1→4)连接,它可以由几千个葡萄糖单元组成。淀粉由直链淀粉和支链淀粉组成。
Estructura del glucógeno.
Estructura de la celulosa.

多糖英语:Polysaccharide)由多个单糖分子脱水聚合,以糖苷键连接而成,可形成直链或者有分支的长链,水解后得到相应的单糖和寡糖。例如用来储存能量的淀粉和糖原,以及用来组成生物结构的纤维素和甲壳素。

多糖常常由略带修饰的重复单元构成。由于结构不同,多糖高分子和构成它的单糖分子性质迥异,可能无定形,甚至不溶于水。

自然界中存在的糖类(如葡萄糖、果糖和甘油醛)一般为单糖,通式为(CH2O)n,其中 n\ge 3。与此相对,多糖的通式为为CxH2O)y,其中x通常在200到2500之间。鉴于多糖通常由六碳糖构成,多糖的通式也可写作(C6H10O5)n,其中 40\le n\le 3000,不过多糖和寡糖的分界见仁见智。

Polysaccharide 多糖

3D structure of cellulose, a beta-glucan polysaccharide.
Amylose is a linear polymer of glucose mainly linked with α(1→4) bonds. It can be made of several thousands of glucose units. It is one of the two components of starch, the other being amylopectin.

Polysaccharides are polymeric carbohydrate molecules composed of long chains of monosaccharide units bound together by glycosidic linkages and on hydrolysis give the constituent monosaccharides or oligosaccharides. They range in structure from linear to highly branched. Examples include storage polysaccharides such as starch and glycogen, and structural polysaccharides such as cellulose and chitin.
