(55,56) These compounds are diagenetic derivatives of photosynthetic pigments, isorenieratene and bacteriochlorophylls e, respectively, from obligately anaerobic green sulfur bacteria.
This hypothesis has been recently boosted by experimental results which reveal long-lived quantum coherent excitonic dynamics in the energy transfer among bacteriochlorophylls in photosynthetic complexes (Engel et al., 2007; Lee et al., 2007).
