Which polysaccharide consists of unbranched chains of D-glucose units linked exclusively by beta-1,4-glycosidic bonds?
Answer and explanation
Correct answer: B. Cellulose
Cellulose is an unbranched linear homopolysaccharide of beta-D-glucose linked by beta-1,4-glycosidic bonds, stabilized by extensive intra- and intermolecular hydrogen bonding into rigid fibrils. Amylose has alpha-1,4 bonds.
