Matching hexose monomers to carbohydrates Steps:

• Identify amylopectin as a branched polymer of α-D-glucose (structure 1).
• Identify cellulose as a linear polymer of β-D-glucose (structure 2).
• Identify sucrose as a disaccharide of α-D-glucose and β-D-fructose (structure 3 for fructose).
• Assign numbers based on primary or distinguishing hexose in each.

Why D is correct:

• Sucrose features β-D-fructose (3), cellulose uses β-D-glucose (2), and amylopectin uses α-D-glucose (1), matching monosaccharide compositions.

Why the others are wrong:

• A misassigns amylopectin to fructose (3) instead of α-D-glucose (1).
• B misassigns cellulose to fructose (3) instead of β-D-glucose (2).
• C misassigns amylopectin to α-D-glucose (1) but swaps sucrose incorrectly (not enough diagram details for full distinction, but mismatches standard pairing).

Final answer: D
