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.
Chitin, a structural polysaccharide found in the exoskeleton of arthropods, differs significantly from cellulose in terms of its monomeric unit. This difference primarily stems from:
The presence of an N-acetyl group at C-2 of the monomer
The type of glycosidic linkage between monomers
The degree of polymerization (chain length)
The three-dimensional arrangement of the polymer chains
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.
In a polysaccharide, the individual monosaccharides are linked by a
Glycosidic bond
