WebThe superchaotropic ions do not exhibit hydrophobic properties but arouse special effects in molecular recognition with macrocyclic hosts and biological interaction with proteins, (9c−e) which influence is much higher than the chaotropic ions (e.g., SCN –) (detailed discussion shown in section 3 ). WebA hydrophobic surface cannot provide a temporary bonding event for a hydrophilic ion. Thus an ion would need an energy source to break the water hydrogen bonding events and not create new hydrogen bonding events. This significant amount of energy is not readily available, which effectively prevents ions from moving through aquaporin channels.
