Saliva is an important component of the taste mechanism. Saliva both interacts with and protects the taste receptors in the mouth. [5] Saliva mediates sour and sweet tastes through bicarbonate ions and glutamate, respectively. [6] The salt taste is induced when sodium chloride levels surpass the concentration in the saliva. [6]
Saltiness taste seems to have two components: a low-salt signal and a high-salt signal. The low-salt signal causes a sensation of deliciousness, while the high-salt signal typically causes the sensation of "too salty". [30] The low-salt signal is understood to be caused by the epithelial sodium channel (ENaC), which is composed of three subunits.

1. If the taste is sour, H+ ions, from an acidic substances, pass through their specific ion channel. Some can go through the Na+ channels. If the taste is salty Na+, sodium, molecules pass through the Na+ channels. Depolarization takes place II. Part II is the transduction pathway of the relay molecules.2.
