The electric field strength of 3.0 V/cm corresponds to become 0.1 fN of electrical force on HBs in the protein, which is virtually six orders of magnitude reduce than the HB bonding Nitrocefin medchemexpress forces. To resolve the inconsistency, Bekard and Dunstan proposed the model of indirect effect (slow approach), that is according to the electrophoretic motion (electrostatic interactions) of a protein major a frictional force for Figure 18.
