Detailed explanation-1: -1. Which is true about the structure of starch molecules and protein molecules? Starches and proteins are both polymers. Starches and proteins are both amino acids.
Detailed explanation-2: -The best explanation for why carbohydrates and proteins are classified as polymers is because they are made up of many similar small units, monomers.
Detailed explanation-3: -Therefore, a protein is made of many monomers called amino acids. Carbohydrate polymers are long chains of repeated simple sugar monomers joined together. For example, as you can see in the diagram below, when many molecules of glucose are joined together, they form a macromolecule called starch.
Detailed explanation-4: -Proteins are polymers in which the 20 natural amino acids are linked by amide bonds.
