In the context of protein structure, what is the monomer (basic building block) of a protein called?
A
Fatty acid
B
Monosaccharide
C
Nucleotide
D
Amino 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 specific molecules that link together to form polypeptide chains.
Identify the options given: Fatty acid, Monosaccharide, Nucleotide, and Amino acid, and recognize their typical biological roles.
Know that fatty acids are building blocks of lipids, monosaccharides are monomers of carbohydrates, nucleotides are monomers of nucleic acids, and amino acids are monomers of proteins.
Conclude that the monomer (basic building block) of a protein is called an amino acid.
