What is the predominant organic molecule in cells formed by long chains of amino acids?

Explanation:
Proteins are polymers formed by linking amino acids into long chains that fold into specific three‑dimensional shapes. This folding and the exact sequence of amino acids give proteins their remarkable diversity, enabling them to act as enzymes, structural components, transporters, hormones, antibodies, and more. Because of this versatility and abundance, proteins are the predominant organic molecules in cells formed from amino acids. Nucleic acids are made of nucleotides and store or transmit genetic information, carbohydrates are sugars that store energy or provide structure, and lipids form membranes and store energy but aren’t built from long chains of amino acids.
