Chlorophyll f
Chlorophyll f is a type form of chlorophyll that absorbs further in the red than other chlorophylls. In 2010, it was reported from stromatolites from Western Australia's Shark Bay.
The finding was made by scientists at the University of Sydney led by Professor Min Chen, and is the first discovery of a new form of chlorophyll in 60 years. However, the function of chlorophyll f in photosynthetic reactions is uncertain and the ecological distribution of chlorophyll f remains unknown. Chlorophyll f has been shown to support some of the roles in photosynthetic reactions, in both the energy transfer and in the charge separation processes.
Based on NMR data, optical and mass spectra and density functional theory simulation, it is confirmed to have a structure of C55H70O6N4Mg or -chlorophyll a.
