Polysaccharide is a glycosidic bond bonded sugar chain, at least more than 10 monosaccharides composed of polymerized sugar polymer carbohydrates, can be used in the general formula (C6H10O5) n said. Polysaccharides composed of the same monosaccharides known as homopolysaccharides, such as starch, cellulose and glycogen; polysaccharides composed of different monosaccharides known as heteropolysaccharides, such as gum arabic is composed of pentose and galactose. Polysaccharide is not a pure chemical substance, but a mixture of substances with different degrees of polymerization. Polysaccharides are generally insoluble in water, have no sweet taste, cannot form crystals, and have no reducibility or change of spin. Polysaccharides are also glycosides, so they can be hydrolyzed, and in the process of hydrolysis, they tend to produce a series of intermediate products, and eventually completely hydrolyzed to obtain monosaccharides.
