How many peptide bonds are present in an insulin molecule?
Correct answer: A. 49
- A. 49
- B. 50
- C. 51
- D. 48
Explanation
There are two polypeptide chains in insulin. One containing 21 amino acids and the other containing 30 amino acids. The bond between the each chain is one less than the total number of the amino acids. In this way the number of peptide bonds will be 49 out of 51 amino acids. So 49 bonds
