Chlorophyll f
chemical compound
Chlorophyll f (Chl f) is a form of chlorophyll that absorbs further into the red (near-infrared light) spectrum than other chlorophylls. In 2010, it was reported by Min Chen to be present in stromatolites from Western Australia's Shark Bay. It has been found in cyanobacteria inside deep caves which appear perfectly dark in the visible light spectrum, but are lit up in near-infrared light which reflects more effectively from the rocks, allowing the cyanobacteria to photosynthesize using light with a wavelength as long as 780nm.
The function of Chl f in photosynthetic reactions in plants and the wider ecological distribution of Chl f remains little studied. 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.
Begin with the source’s own compact description: “Chlorophyll f” is chemical compound. The dossier treats that line as a proposition to test through Chlorophyll, chemical and compound, not as a finished interpretation.
Why this record matters
The phrase “chemical compound” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Feb 3, 2026. The linked authority identifier is Q82129. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2010.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
