Chlorophyll f

Chlorophyll f is a type form of chlorophyll that absorbs further in the red (infrared light) than other chlorophylls.[2][3] In 2010, it was reported from stromatolites from Western Australia's Shark Bay.[4]

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.[4] 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.[5][6][7]

Based on NMR data, optical and mass spectra and density functional theory (DFT) simulation, it is confirmed to have a structure of C55H70O6N4Mg or [2-formyl]-chlorophyll a.[1][2]
