What are the basic components of proteins?

• A. Nucleic acids
• B. Monosaccharides
• C. Lipids
• D. Amino acids

Answer: (D)

Proteins are polymers made from amino acids, the basic units that determine a protein’s structure and function. Each amino acid has an amino group, a carboxyl group, a hydrogen, and a variable side chain (R-group). The amino acids are linked together by peptide bonds in a specific sequence, and this order drives how the protein folds and what it does in the cell. Other biomolecules use different building blocks: nucleic acids are built from nucleotides, carbohydrates from monosaccharides, and lipids from fatty acids and glycerol. So, the fundamental components that make up proteins are amino acids.
