Detailed explanation-1: -Maltose consists of two molecules of glucose that are linked by an -(1, 4β) 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.
Detailed explanation-2: -Glucose-(1 β 4)-glucose is the backbone glycosidic linkage in three abundant biological storage polysaccharides: amylose, amylopectin, and glycogen. Experimental and computational investigations have shown that the (1 β 4)-glycosidic bond in glucans is conformationally restricted.
Detailed explanation-3: -In maltose the glycosidic oxygen atom of one glucose is and is bonded to the C-4 atom of another glucose unit that is the aglycone. Therefore, maltose is an -1, 4ΚΉ-glycoside.
Detailed explanation-4: -Amylose is a linear polymer of glucose molecules linked by -1, 4-glycosidic linkages.
