Joy of Sharing ScienceF O R M A T I O N O F S O A PA saponification reaction is composed of an ester reacting with a base to create acarboxylate ion and alcohol.The mechanism is as follows:The Hydroxide from the base performs a nucleophilic attack on the carbonylcarbon. This produces a tetrahedral intermediate with a negatively charged oxygenatom.The electrons from the Oxygen cause the O-R group to leave.
What makes soap so essential against viral infection?The leaving group and the remaining group rapidly exchange a proton to reach thefinal products.When this mechanism is applied to a triglyceride molecule, common soap isacquired.Soaps, like all detergents, have both a nonpolar hydrocarbon tail and a polar head.This hydrophobic tail is attracted to other non polar molecules such as lipids whilethe hydrophilic head is attracted to polar water molecules.S O A P A G A I N S T C O V I D - 19The outer layer of the coronaviruses are made up of lipids, and so there is anattraction between the hydrophobic side of soap molecules and the lipid outerlayer. While hydrophobic tails of soap molecules compete for space with the lipidsthat make up the outer shell of the virus, the hydrophilic side of the molecule isattracted to the water molecules present in the environment.
