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.
