Guida verificata passo dopo passo1
Understand the structure of proteins: Proteins are macromolecules made up of smaller repeating units called monomers.
Recall the specific type of monomer that forms proteins: Proteins are constructed from amino acids, which are organic compounds containing both an amino group (-NH₂) and a carboxyl group (-COOH).
Eliminate incorrect options: Nucleotides are the building blocks of nucleic acids (DNA and RNA), monosaccharides are the monomers of carbohydrates, and fatty acids are components of lipids.
Focus on the correct option: Amino acids are the monomers that link together through peptide bonds to form polypeptides, which fold into functional proteins.
Conclude the reasoning: Proteins are polymers constructed specifically from amino acid monomers, making this the correct answer.
