The adherent mucoid alkaline substance covering the inner lining of the stomach serves to prevent the action of pepsin on the mucosa. Option 1, digesting starch, is not related to the protective function of the mucoid substance. Option 2, acting against bacteria, is not the primary purpose of this substance, although it may have some protective effects. Option 4, preventing viral infection, is not a function of the mucoid substance.

The acidic environment in the stomach can be harmful to the stomach lining. Pepsin, an enzyme produced by the stomach, helps break down proteins but can also damage the mucosa if not controlled. The adherent mucoid alkaline substance acts as a protective barrier, neutralizing the acid and preventing the action of pepsin on the mucosa. This prevents damage to the stomach lining and maintains its integrity.
