Question

A short peptide on complete hydrolysis produces 3 moles of glycine (G), two moles of leucine (L) and two moles of valine (V) per mole of peptide. The number of peptide linkages in it are  .

Canvas Classes · Accepted Answer

Counting peptide linkages:

The peptide contains: 3G + 2L + 2V = 7 amino acid residues total.

Key relationship:
For a linear peptide with  amino acid residues:

Reasoning: Each peptide bond forms between the –COOH of one amino acid and the –NH₂ of the next, releasing water. For 7 amino acids joined in a chain, 6 peptide bonds are formed.

Final Answer: 6
