Question

amino acids are linked by a specific type of covalent bond. the reaction producing this bond also produces one water molecule. what type of bond links amino acids together in a chain? a) hydrogen bonds b) peptide bonds c) metallic bonds d) ionic bonds

Explanation:

To determine the bond linking amino acids, we analyze each option:

• Option a: Hydrogen bonds are weak intermolecular forces, not for linking amino acids in a chain.
• Option b: Peptide bonds form between amino acids via a dehydration reaction (producing water), which matches the description.
• Option c: Metallic bonds occur in metals, not in amino acid chains.
• Option d: Ionic bonds involve ion attraction, not amino acid linkage.

Answer:

b) Peptide bonds
