A taste receptor is a type of receptor which facilitates the sensation of taste. When food or other substances enter the mouth, molecules interact with saliva and are bound to taste receptors in the oral cavity and other locations. Molecules which give a sensation of taste are considered sapid.he TAS1R2 + TAS1R3 heterodimer receptor functions as the sweet receptor by binding to a wide variety of sugars and sugar substitutes. TAS1R2+3 expressing cells are found in circumvallate papillae and foliate papillae near the back of the tongue and palate taste receptor cells in the roof of the mouth.
Taste buds contain receptor cells for taste stimuli are located in structures. Some taste buds are also found on the soft palate, epiglottis and lower oral pharynx. There are three types of taste buds: Basal cells, Supporting Cells, and Sensory cells (sometimes called taste receptor cells).
