Verified step by step guidance

Understand the question: The problem is asking about the biological macromolecule that amino acids serve as building blocks for. This requires knowledge of the structure and function of macromolecules in biochemistry.

Recall the definition of amino acids: Amino acids are organic compounds that contain both an amino group (-NH₂) and a carboxyl group (-COOH). They are the monomers that combine to form larger macromolecules.

Identify the macromolecule: Proteins are composed of amino acids linked together by peptide bonds. Proteins are synthesized through the process of translation, where amino acids are joined in a specific sequence dictated by mRNA.

Eliminate incorrect options: Nucleic acids are composed of nucleotides, carbohydrates are composed of monosaccharides, and lipids are composed of fatty acids and glycerol. None of these macromolecules use amino acids as their building blocks.

Conclude: Amino acids are the building blocks of proteins, which are essential for structural, enzymatic, and signaling functions in living organisms.
