As shown in Figure 1, T2R38 is a bitter taste receptor located on ciliated cells in humans, and it responds to at least three AHLs produced by P.
Studies have revealed two classes of GPCRs that have been identified, including taste 1 receptor family (T1R) and the taste 2 receptor family (T2R), and two subtypes of the T1R family, including T1R member 2 (T1R2) and T1R member 3 (T1R3), form heterodimers to act as sweet taste receptors (STRs), which are expressed in taste buds and in the gastrointestinal tract and respond to various chemically distinct compounds, such as natural sugars, noncaloric artificial and natural sweeteners, some D-amino acids, and sweet-tasting proteins [7].

In vertebrates, they are coded by six major multigene families: the trace amine-associated receptors (TAAR) [5], the olfactory receptors (OR) [6], the type I and II vomeronasal receptors (V1R and V2R) [3, 4, 7], and type I and II taste receptors (T1R and T2R) [1, 2].

(16) Bitter taste receptor activation has been associated with a rapid change in the level of second messengers.
A taste bud is a group of 50 to 150 cells called taste receptors. (Under a microscope, this bundle of cells looks a little like a big bunch of bananas.) The tips of the taste receptor cells pick up tastes in the mouth, and then send that information to the brain.
