A dipeptide have an/a _ group at one end and a _ group at the other end of molecule.
Correct answer: A. Amino, Carboxyl
- A. Amino, Carboxyl
- B. Amino, Functional
- C. Functional, Carboxyl
- D. Amino, Amino
Explanation
A dipeptide consists of two amino acids joined by a peptide bond. This bond forms between the amino group of one amino acid and the carboxyl group of the other. As a result, a dipeptide has an amino group at one end (N-terminus) and a carboxyl group at the other end (C-terminus). Options B, C, and D are incorrect because they either misidentify or omit the essential carboxyl group, or incorrectly suggest identical groups at both ends.

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.
