The hydrogen bonds, which are central features of protein structures, then what is the reason behind it makes only minor contributions to protein stability?

#Unit 1. Molecules and their Interaction Relevant to Biology

  1. hydrogen bond is weak interaction that’s why not involve in protein stability

  2. Because hydrogen-bonding groups in an unfolded protein form hydrogen bonds with water molecules

  3. stabilizing energy of the hydrogen bond would be lost

  4. because huydrogen bonding are not the part of the folding process
