Question 11

Amylose is a component of starch, a storage polysaccharide found in plants.

Which option correctly describes how the structure of amylose relates to its function?

The presence of 1-61\text{-}61-6 glycosidic bonds creates a highly branched structure leading to rapid mobilization of energy.

Alternating β\betaβ-glucose monomers rotate by 180∘180^\circ180∘ to form straight, unbranched chains with high tensile strength.

The coiled, helical conformation stabilizes the molecule and makes it compact, allowing efficient storage in a small space.

It is highly soluble because of many exposed −OH-\text{OH}−OH groups, which prevents it from osmotic precipitation.
