검증된 단계별 안내1
Identify the four major types of macromolecules: proteins, nucleic acids, lipids, and carbohydrates.
Understand that proteins are polymers made up of monomers called amino acids.
Recognize that nucleic acids are composed of nucleotides, which are different from amino acids.
Note that lipids are not polymers and are primarily composed of fatty acids and glycerol.
Acknowledge that carbohydrates are made up of sugar monomers, not amino acids, confirming that proteins are the macromolecules made up of amino acids.
