Proteins are polymers made from which monomers?

Proteins are polymers made from which monomers?

• A. Nucleotides
• B. Amino acids
• C. Fatty acids
• D. Sugars

Answer: (B)

Proteins are polymers built from amino acids, the monomer units that link together to form long polypeptide chains through peptide bonds. The specific sequence and arrangement of amino acids determine how the protein folds and works in the body. Other options point to different types of biomolecules: nucleotides make up nucleic acids like DNA and RNA; fatty acids are parts of lipids; sugars are the monomers of carbohydrates. So amino acids are the monomers that make up proteins.
