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

hydrogen bond is weak interaction that’s why not involve in protein stability
Because hydrogen-bonding groups in an unfolded protein form hydrogen bonds with water molecules
stabilizing energy of the hydrogen bond would be lost
because huydrogen bonding are not the part of the folding process
