Chlorophyll f

Chlorophyll f (Chl f) is a type form of chlorophyll that absorbs further in the red (infrared light) than other chlorophylls. In 2010, it was reported by Min Chen to be present in stromatolites from Western Australia's Shark Bay.

The function of Chl f in photosynthetic reactions is uncertain and the ecological distribution of Chl f remains unknown. Chl f has been shown to support some of the roles in photosynthetic reactions, in both the energy transfer and in the charge separation processes.

Chl f is produced from chlorophyllide f by chlorophyll synthase. Chlorophyllide f is made from chlorophyllide a by an enzyme known as PsbA4 or ChlF.
