In biochemistry, what is the monomer (building block) of a protein?
A
A monosaccharide
B
An amino acid
C
A nucleotide
D
A fatty acid
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 the building blocks that link together to form polypeptide chains.
Identify the four options given: monosaccharide, amino acid, nucleotide, and fatty acid, and recognize which biomolecules they are associated with (e.g., monosaccharides with carbohydrates, nucleotides with nucleic acids, fatty acids with lipids).
Know that amino acids are the specific monomers that polymerize to form proteins through peptide bonds.
Conclude that the correct monomer of a protein is an amino acid.
