What term correctly describes the building blocks that make up proteins?

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

Answer: (A)

Proteins are built from amino acids. These small molecules link together in chains called polypeptides through peptide bonds, and the sequence of amino acids determines how the protein folds into its final shape and function. About 20 standard amino acids give proteins their diverse properties because each has a different side chain that influences chemistry and structure. Monosaccharides form carbohydrates, fatty acids make up fats and membranes, and nucleotides build nucleic acids like DNA and RNA. So the term that correctly describes the building blocks of proteins is amino acids.
