검증된 단계별 안내1
Understand that proteins are macromolecules essential for various biological functions, including catalysis, structural support, and transport.
Recognize that proteins are composed of smaller units called monomers, which are linked together to form a polymer.
Identify the correct monomers of proteins: amino acids. These are organic compounds that combine to form proteins.
Amino acids have a basic structure consisting of an amino group (NH₂), a carboxyl group (COOH), a hydrogen atom, and a variable R group or side chain, all attached to a central carbon atom.
Note that other options like glucose molecules, lipids, and nucleotides are monomers for different macromolecules: carbohydrates, fats, and nucleic acids, respectively.
