Amylose as a glucose polymer

Steps:

• Identify amylose as a component of starch, a carbohydrate.
• Classify amylose as a polysaccharide, a large carbohydrate.
• Recognize polysaccharides as polymers formed by linking monomers.
• Specify glucose as the monosaccharide monomer in amylose.

Why D is correct:

• Amylose is defined as a polysaccharide, a polymer of glucose monosaccharide units linked by glycosidic bonds.

Why the others are wrong:

• A: Uses incorrect terms; amylose is a polysaccharide polymer, not a macromolecule monomer or disaccharide.
• B: Wrongly calls glucose a disaccharide; glucose is a monosaccharide.
• C: Identical to B, so same error in classifying glucose.

Final answer: D
