55,56) These compounds are diagenetic derivatives of photosynthetic pigments, isorenieratene and bacteriochlorophylls e, respectively, from obligately anaerobic green sulfur bacteria.
The basic structure of geoporphyrins, especially those with an exocyclic ring in the southern part of the molecule, is strongly suggestive of origin from chlorophylls and bacteriochlorophylls, which are major photosynthetic pigments of photoautotrophs.
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.
