A linear polysaccharide chain contains 10 covalently linked glucose units. After complete digestion in the small intestine, how many glucose monomers will be available to be absorbed into the blood?

• A. 20 monosaccharides, because each glucose splits into two smaller sugars during absorption.
• B. 0, since humans cannot digest polysaccharides and they pass intact to the large intestine.
• C. 5 glucose monomers, because digestion cleaves every other bond and reduces the total by half.
• D. 10 glucose monomers.

Answer: (D)
