Question

Identify the incorrect statement from the following:

Options

• Glycogen is called as animal starch.

• β-Glycosidic linkage makes cellulose polymer.

• Amylose is a branched chain polymer of glucose.

• Starch is a polymer of α-D-glucose.

Answer 1

Amylose is a branched chain polymer of glucose.

Explanation:

Glycogen, a type of glucose that is stored, is a polysaccharide also referred to as animal starch. Cellobiose residues serve as repeating units of the polysaccharide known as cellulose, which is composed of linear glucose chains connected together by β-1, 4-glycosidic linkage.

Amylose and amylopectin, two polysaccharides, are combined to form starch. Amylose is a linear chain polymer and amylopectin is a branched polymer. α-1, the 4-glycosidic linkage is used in amylase to join units of α-D-glucose. α-glucose is joined through α-1, 4-glycosidic linkage and in between by α-1, 6-glycosidic linkage in the branching polysaccharide known as amylopectin.

Therefore, amylase is a linear chain polymer of α-D-glucose.
