dc.description.abstract | An important characteristic that determines the behavior of a solute in water is whether it is hydrophobic or hydrophilic. The traditional
classification is based on chemical experience and heuristics. However, this does not reveal how the local environment modulates this important property. We present a local fingerprint for hydrophobicity and hydrophilicity inspired by the two body contribution to the entropy.
This fingerprint is an inexpensive, quantitative, and physically meaningful way of studying hydrophilicity and hydrophobicity that only
requires as input the water-solute radial distribution functions. We apply our fingerprint to octanol, benzene, and 20 proteinogenic amino
acids. Our measure of hydrophilicity is coherent with chemical experience, and moreover, it also shows how the character of an atom can
change as its environment is changed. Finally, we use the fingerprint as a collective variable in a funnel metadynamics simulation of a
host-guest system. The fingerprint serves as a desolvation collective variable that enhances transitions between the bound and unbound
states. | es |
