Abstract
Background: Phototrophic prokaryotes inhabit a diverse array of environments on our planet and also contain a wide range of chlorophylls and bacteriochlorophylls, encompassing both chlorin and bacteriochorin structures.
Objective: This review considers the ecological niches of the phototrophic prokaryotes, together with the mass spectrometric study of their chlorophyll and bacteriochlorophyll pigments.
Methods: A thorough review of the mass spectrometry literature on chlorophylls from phototrophic prokaryotes has been carried out.
Results: Mass spectrometry, particularly coupled with liquid chromatography and used in conjunction with soft ionization techniques, has been pivotal in the assignment of closely related chlorophyll and bacteriochlorophyll structures from these organisms.
Conclusion: Exploration of our natural environment continues to find previously uncharacterized photosynthetic prokaryotes, utilizing subtle but significant modifications to the chlorophyll and bacteriochlorophyll structures in our current knowledge.
Keywords: Bacteriochlorophyll, chlorophyll f, chlorophyll d, fragmentation, liquid chromatography/mass spectrometry, photosynthetic bacteria.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
