6.8: Polysaccharides - Chemistry LibreTexts

WebbImportance of Polysaccharides. When many monosaccharide units are joined together by a glycosidic linkage then polysaccharides are formed. These are commonly found in nature. They also act as food storage or structural materials. First, let us discuss starch from where we will move on to other polysaccharides such as Glycogen and Cellulose. WebbMaltose. Maltose consists of two molecules of glucose that are linked by an α- (1,4’) glycosidic bond. Maltose results from the enzymatic hydrolysis of amylose, a homopolysaccharide (Section 28.9 ), by the enzyme amylase. Maltose is converted to two molecules of glucose by the enzyme maltase, which hydrolyzes the glycosidic bond. embassy hotel birmingham al https://urbanhiphotels.com
