The scientific work of Charles-Augustin de Coulomb has transcended as a significant contribution to explain phenomena in nature and generate crucial technological development in recent daily activities. We used Coulomb’s law to calculate the changes generated in the electrostatic interactions of residue 614 of SARS-CoV-2 Spike protein when the D614G mutation occurs. We made a physical analysis of the transformation and the biological implications in the whole molecule’s structural stability, obtaining that a greater electronegativity of the mutation stage favors the open state of Spike, which is manifested as a greater efficiency to bind to the ACE2 human receptor.
