Which term will we use when the two amino acids join each other?
Correct answer: B. Dipeptide
- A. Monopeptide
- B. Dipeptide
- C. Tripeptide
- D. Tetrapeptide
Explanation
The correct answer is Option B: Dipeptide. When two amino acids are joined together by a peptide bond, the resulting molecule is called a dipeptide. Option A, Monopeptide, is incorrect because it refers to a single amino acid. Option C, Tripeptide, is also incorrect, as it involves three amino acids. Option D, Tetrapeptide, is incorrect because it involves four amino acids. Both of these options contain more than the two amino acids specified in the question.
