Amylose, a component of starch, is composed of glucose monomers linked predominantly by which type of glycosidic bond?
ฮฑ-1,4-glycosidic bonds
ฮฒ-1,4-glycosidic bonds
ฮฑ-1,6-glycosidic bonds
ฮฒ-1,6-glycosidic bonds
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 ฮฒ(2โ1) glycosidic bonds, while starch primarily consists of glucose units linked by ฮฑ(1โ4) and ฮฑ(1โ6) bonds.
Amylopectin, a component of starch, is characterized by:
Linear chains of ฮฒ-D-glucose
Branched chains of ฮฑ-D-glucose
Linear chains of fructose
Branched chains of N-acetylglucosamine
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.
Which structural characteristic of cellulose prevents it from forming a blue color with iodine?
ฮฑ-1,4-glycosidic linkages
ฮฒ-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.
