Inulin, a storage polysaccharide found in some plants, differs from starch in several key aspects. Which of the following statements accurately describes a major difference between inulin and starch?
Inulin is a branched polymer, while starch is strictly linear.
Inulin is primarily found in animals, while starch is found in plants.
Inulin forms a helical structure, while starch forms a sheet-like structure.
Inulin is composed of fructose units linked by β(2→1) glycosidic bonds, while starch primarily consists of glucose units linked by α(1→4) and α(1→6) bonds.

Which structural characteristic of cellulose prevents it from forming a blue color with iodine?
α-1,4-glycosidic linkages
β-1,4-glycosidic linkages
Presence of fructose units
Branched polymer structure
Iodine forms a blue color complex with starch but not with cellulose. This difference is primarily due to:
The presence of branching in cellulose.
The higher molecular weight of cellulose.
Difference in glycosidic linkages and resulting structural conformations.
The different monomer composition of cellulose and starch.
Why doesn't cellulose react with iodine to produce a blue color?
It lacks the helical structure necessary for iodine complexation.
It contains fructose units instead of glucose.
It is a branched polymer and cannot interact with iodine.
It is insoluble in water, preventing the reaction with iodine.
Amylopectin, a component of starch, is characterized by:
Linear chains of β-D-glucose
Branched chains of α-D-glucose
Linear chains of fructose
Branched chains of N-acetylglucosamine
The monomer unit of starch is:
Fructose
Galactose
Sucrose
Glucose
