Verified step by step guidance

Understand the structure of proteins: Proteins are macromolecules made up of smaller building blocks called monomers. These monomers are linked together in a chain to form the polymer structure of proteins.

Identify the correct monomer: Proteins are composed of amino acids, which are organic molecules containing both an amino group (-NH₂) and a carboxyl group (-COOH). These amino acids are connected by peptide bonds to form the protein chain.

Eliminate incorrect options: Fatty acids are components of lipids, not proteins. Monosaccharides are the building blocks of carbohydrates, and nucleotides are the monomers of nucleic acids like DNA and RNA.

Recognize the polymerization process: Amino acids are joined together through a dehydration synthesis reaction, where a water molecule is removed to form a peptide bond between the amino group of one amino acid and the carboxyl group of another.

Conclude that proteins are polymers of amino acids: Based on the structural and functional characteristics of proteins, the correct answer is amino acids.
