Verified step by step guidance1
Understand that proteins are large biomolecules made up of smaller repeating units called monomers or subunits.
Recall that the primary monomeric building blocks of proteins are amino acids, which link together via peptide bonds to form polypeptides.
Recognize that fatty acids are the building blocks of lipids, monosaccharides are the monomers of carbohydrates, and nucleotides are the monomers of nucleic acids.
Therefore, identify that the correct monomeric building block of a protein is an amino acid.
Summarize that proteins are polymers of amino acids, which determine the protein's structure and function.
