Cellulose and amylose are ________.
A) 1,4' linked polymers of D-glucose which differ in the stereochemistry of this linkage
B) 1,6' linked polymers of D-glucose which differ in the stereochemistry of this linkage
C) polymers of D-glucose which are structurally isomeric
D) polymers of D-galactose which are structurally isomeric
E) synonyms for the only polymeric form of D-glucose

Question

Quizplus · Accepted Answer

Cellulose and amylose are both polymers of D-glucose, but they differ in the stereochemistry of the 1,4' linkage between glucose units. Amylose is an unbranched polymer of glucose units linked by α-1,4 glcosidic bonds, while cellulose is a linear polymer of β-1,4 linked glucose units.
