IR75q.1 orthologues responded to octanoic acid and other medium‐chain fatty acids. Left panel of each receptor: Response profile of the receptor to the different odors. Response magnitudes were normalized to the average response of primary ligand (N ≥ 4). Error bars indicate the SEM. Middle panel of each receptor: Dose‐dependent responses, showing values normalized to the average response of the most active compound at 1 mM (N ≥ 4 for each ligand). Right panel of each receptor: Representative current trace of oocytes upon successive exposures to 10 μM stimuli. Each compound was applied at the time indicated by the arrowheads for 10 s. Individual data values are listed in Additional file 3
