Talking bacteria: The combination of NMRspectroscopy and 4,5‐dihydroxy‐2,3‐pentanedione (DPD) homologue analysis reveals that DPD, a bacterialsignaling compound in the autoinducer‐2 (AI‐2) class (see scheme), exists as a much more complex structural array of molecules than previously appreciated. This finding suggests the existence of a larger bacterial chemical signaling language than previously thought
