TAS2R16 (taste receptor, type 2, member 16) is a bitter taste receptor and one of the 25 TAS2Rs. TAS2Rs are receptors that belong to the G-protein-coupled receptors (GPCRs) family. These receptors detect various bitter substances found in nature as agonists, and get stimulated. TAS2R16 receptor is mainly expressed within taste buds present on the surface of the tongue and palate epithelium.[5] TAS2R16 is activated by bitter β-glucopyranosides (such as salicin)[6]
