Explanation:
Detailed explanation-1: -Maltose consists of two molecules of glucose that are linked by an -(1, 4′) glycosidic bond. Maltose results from the enzymatic hydrolysis of amylose, a homopolysaccharide (Section 26.9), by the enzyme amylase. Maltose is converted to two molecules of glucose by the enzyme maltase, which hydrolyzes the glycosidic bond.
Detailed explanation-2: -In maltose, the two units of glucose are in the pyranose form. An O-glycosidic bond joins these units.
Detailed explanation-3: -Maltose is produced by the enzymatic hydrolysis of starch (a homopolysaccharide) catalyzed by the enzyme amylase. Maltose is further hydrolyzed by the enzyme maltase to produce two molecules of d-glucose.
