Question

2. If decomposition of biomolecules, for instance the hydrolysis of the peptide bonds, is an energetically favorable reaction, how can our proteins appear to be stable and functional in other words, how can life continue to exist and flourish in such a situation?

Answer 1

Hydrolysis of peptide bond goes in the following pathway. RindR2+10RE Artete Zt Although the hydrolysis af peptide bonds is thermodyna- mically favoured. Such ny trolysis reactions are very slow In the absence of catalyst a typical peptide hydrolysis at neutral pH may be as long as years. The chemical bonding in peptide bonds are responsible in this kinetic stability and inertness towards decomposition specifically the resonance structure of plomarity of peptike bond. This is just an example. Every biomolecule is enabled to disintegrated in minutes by a backdocat as thermal favourite But sometimes their structure, ory their spin state (singut or triplet) or their orientation gives them the kinetic stability to survive.
