In biochemistry, what are the building blocks (monomers) of proteins called?
A
Fatty acids
B
Nucleotides
C
Amino acids
D
Monosaccharides
Verified step by step guidance1
Understand that proteins are large biomolecules made up of smaller units called monomers.
Recall that the monomers of proteins are specific molecules that link together to form polypeptide chains.
Identify the four options given: Fatty acids, Nucleotides, Amino acids, and Monosaccharides.
Recognize that fatty acids are the building blocks of lipids, nucleotides are the monomers of nucleic acids, and monosaccharides are the monomers of carbohydrates.
Conclude that the correct monomers of proteins are amino acids, which contain an amino group, a carboxyl group, and a unique side chain.
