Verified step by step guidance

Understand the question: The problem is asking about the macromolecule that amino acids serve as monomers for. Monomers are the building blocks of larger macromolecules.

Review the structure of amino acids: Amino acids consist of an amino group (-NH₂), a carboxyl group (-COOH), a hydrogen atom, and a unique side chain (R group) attached to a central carbon atom.

Recall the macromolecules: The four major types of macromolecules are polysaccharides (carbohydrates), proteins, nucleic acids, and lipids. Each has specific monomers associated with its structure.

Connect amino acids to proteins: Proteins are composed of amino acids linked together by peptide bonds. These bonds form during a condensation reaction between the amino group of one amino acid and the carboxyl group of another.

Eliminate incorrect options: Polysaccharides are made of monosaccharides, nucleic acids are made of nucleotides, and lipids are not composed of amino acids. Therefore, the correct macromolecule associated with amino acids is proteins.
