Question

Issues of stability. Proteins are quite stable. The lifetime of a peptide bond in aqueous solution is nearly 1000 years. However, the free energy of hydrolysis of proteins is nega- tive and quite large. How can you account for the stability of the peptide bond in light of the fact that hydrolysis releases much energy

Answer 1

The Resonance present between the bonds amino atom and carboxyl atom.

Explanation:

• A Peptide bond is a covalent linkage between two amino groups of proteins.
• A Peptide bond is a covalent bond that is present between the two protein molecules that are carboxyl group -COOH of one molecule of protein and the amino group  -NH2 of other molecules of protein.
• A Peptide bond is stable as the hydrolysis process is very slow which is due to the resonance present between the bonds.
• Hydrolysis releases much energy as the Peptide bond is the most durable covalent type of bond.
