Verified step by step guidance1
Understand that proteins are large biological molecules made up of smaller repeating units called monomers.
Recall that the monomers of proteins are specific molecules known as amino acids, which link together via peptide bonds to form polypeptides.
Recognize that fatty acids are the monomers of lipids, monosaccharides are the monomers of carbohydrates, and nucleotides are the monomers of nucleic acids, so these are not the building blocks of proteins.
Therefore, identify amino acids as the correct type of monomer units that make up proteins.
Summarize that proteins are polymers composed of amino acid monomers linked in a specific sequence to form functional proteins.
