The composition and stoichiometry of bitter taste receptors is not yet established. Bitter receptors appear to separate into two groups, with very restricted ligand specificity or much broader responsiveness. For example, T2R5 responded to cycloheximide, but not 10 other bitter compounds [2], while T2R14 responded to at least eight different bitter tastants, including (-)-α-thujone and picrotoxinin [1].

Specialist database BitterDB contains additional information on bitter compounds and receptors [6].
