What forms the building blocks of protein?

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

Answer: (A)

Amino acids are the building blocks of proteins. Proteins are polymers made by linking amino acids together through peptide bonds in a process called dehydration synthesis. The sequence of amino acids—the primary structure—dictates how the chain folds into secondary, tertiary, and quaternary structures, driven by interactions among the side chains (R groups). Those shapes determine the protein’s chemical properties and functions, from enzymes and structural components to signaling and transport. The other options refer to monomers for different biomolecules: nucleotides form nucleic acids, fatty acids form lipids, and sugars form carbohydrates.
