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. [2] [3]

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. [4] [5] [6]

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. [7]
