Which of the following is the polysaccharide, which produces cellobiose and β-D-glucose on hydrolysis?
This fibrous structural polysaccharide is present in abundance in the plant cell walls but absent in animals.
-
Peptidoglycan
-
Hyaluronic acid
-
Starch
-
Inulin
-
Cellulose
E
Correct answer
Explanation
Cellulose on hydrolysis produces cellobiose and β-D-glucose. The first step involves breaking of β-glycosidic bonds with the help of β-1, 4 glucanase to form cellobiose. Then, the β-1, 4 glycosidic bond is cleaved with the help of β-glucosidase to form glucose.
