Properties of Starches

BIOCHM-AR7YKR

Amylose and amylopection are large homopolymers of glucose that are the major forms of starch in plants.

What is the primary difference between amylose and amylopectin?

A

Amylose contains $\alpha1\rightarrow4$ glycosidic bonds and amylopection contains $\beta1\rightarrow4$ glycosidic bonds.

B

Amylose contains only $\alpha1\rightarrow4$ glycosidic bonds and amylopectin contains only $\alpha1\rightarrow6$ glycosidic bonds.

C

Amylose is a linear chain of only $\alpha1\rightarrow4$ glycosidic bonds while amylopectin has multiple $\alpha1\rightarrow6$ branch points in addition to $\alpha1\rightarrow4$ glycosidic bonds.

D

Amylose is a linear chain of only $\alpha1\rightarrow4$ glycosidic bonds while amylopectin has multiple $\alpha1\rightarrow3$, $\alpha1\rightarrow5$, and $\alpha1\rightarrow6$ branch points in addition to $\alpha1\rightarrow4$ glycosidic bonds.
