This is because hydrogen-bonding groups in an unfolded protein form hydrogen bonds with water molecules. Thus the contribution of a hydrogen bond to the stability of a native protein is the small difference in hydrogen bonding free energies between the native and unfolded states (−2 to 8 kJ ∙ mol−1)

Loss of the zeta population 

Epidermal cell types do not fully regenerate in the absence of zeta neoblasts, the remaining neoblasts (likely sigma) and their derived cell types are unaffected.
