Force extension curves for polymers with hydrophobic patches: Role of
Disorder
   [PDF]

Ankur Mishra, Ajay S. Panwar, Buddhapriya Chakrabarti
Motivated by single molecule experiments on biopolymers we explore force vs.\ extension behavior of flexible chains with hydrophobic segments using numerical simulations and theory. We find that in addition to the fraction of hydrophobic patches their spatial distribution along the backbone of the chain play a major role in altering its mechanical response. These results are discussed in light of the helix-coil model for biopolymers.
