Which of the following bond is responsible for joining the amino acids in proteins?
Correct answer: A. Peptide Bond
- A. Peptide Bond
- B. Ionic Bond
- C. Metallic Bond
- D. Disulfide Bond
Explanation
Option A is correct, as within a protein chain, each amino acid is linked to each other by a peptide bond which is a covalent bond.Options B and D describe those bonds that hold proteins in their complex three dimensional structures, but the question asks for the bond that holds individual amino acids within proteins.Option C describes a metallic bond which is only found in metals, and not in proteins as it is molecular in nature.

About Macromolecules
Proteins are classified by shape, composition and structure, from primary amino acid sequence to secondary, tertiary and quaternary organisation, and their biological roles are linked to this structure. Enzymes are examined as protein biocatalysts, including active sites, substrate specificity, activation energy, cofactors and factors affecting activity.
