Question

A peptide synthesised by the reactions of one molecule each of Glycine, Leucine, Aspartic acid and Histidine will have ____ peptide linkages.

• A. 3.0
• B. 3.00
• C. 3

Answer 1

Answer: (A), (B), (C)

Combination of $n$ amino acids gives a polypeptide with $(n-1)$ peptide linkages.

Similarly combination of four amino acids gives a tetrapeptide with three peptide linkages.
Hence, answer is 3.
