What is the polymer formed by many amino acids connected by peptide bonds?

• A. Polypeptide
• B. Nucleic acid
• C. Polysaccharide
• D. Lipid

Answer: (A)

Amino acids linked by peptide bonds form a polypeptide. A peptide bond is a covalent link between the carboxyl group of one amino acid and the amino group of the next, created through dehydration synthesis. A long chain of these linked amino acids is called a polypeptide, and when one or more polypeptides fold and function together, the molecule is a protein. The other options refer to different kinds of biopolymers: nucleic acids are made from nucleotides connected by phosphodiester bonds, polysaccharides are made from sugar units linked by glycosidic bonds, and lipids are not polymers formed by repeating monomers in the same sense.
