Which description best expresses the primary functional objective of carbohydrate digestion in the human GI tract?

• A. To polymerize simple sugars into insoluble complexes in the stomach before they reach the colon, a process that contradicts the digest-and-absorb objective of carbohydrate digestion.
• B. To enzymatically cleave complex carbohydrates into monosaccharides small enough for intestinal absorption.
• C. To hydrolyze dietary proteins into monosaccharides and then reconjugate them into disaccharides within the stomach to slow gastric emptying and improve absorption of lipids in the small intestine, a claim mixing macronutrient processes and incorrect enzyme targets.
• D. To convert structural fibers into amino acids for systemic protein synthesis, which misstates fiber fate and macronutrient pathways.

Answer: (B)
