Linear polymers formed by linking the carboxyl group of amino acids are called

• A. Amino acids
• B. Polypeptides
• C. Nucleic acids
• D. Proteins

Answer: (D)

When amino acids join through peptide bonds between the carboxyl group of one amino acid and the amino group of the next, they form a chain called a polypeptide. This is the linear polymer made up of amino-acid units. If that polypeptide folds and gains a specific 3D structure to perform a function, it becomes a protein. So the term for the linear polymer created by linking the carboxyl groups is polypeptide, with proteins referring to the functional, folded forms those chains can adopt.
