Quizplus · Accepted Answer

Cellulose and starch both consist of a long chain of glucose molecules (property I), but cellulose differs from starch in that its monosaccharide units are connected by beta linkages (property II), whereas starch has alpha linkages. Additionally, the neighboring monosaccharides in cellulose form hydrogen bonds (property III), which provides the rigid structure important for cell walls, whereas starch does not have such a structure. Finally, cellulose is not easily broken down by enzymes in the body, whereas starch is (property IV).
