How many bonds are in a dipeptide?
Correct answer: A. 1
- A. 1
- B. 2
- C. 4
- D. 2/4
Explanation
A dipeptide is formed when two amino acids are joined by a single peptide bond. This bond is a covalent bond that specifically links the carboxyl group of one amino acid to the amino group of another, releasing a molecule of water in the process. While other interactions and bonds may exist within the overall structure of proteins, the question specifically asks about the bonds in a dipeptide, which is singular: 1 peptide bond. Options B, C, and D incorrectly count additional or irrelevant bonds that do not contribute to the peptide linkage.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
