DETAILS

Description (English)
Biochem/physiol Actions
Chlorophyll b extends the absorption spectrum of light-harvesting complexes LHC-I and LHC-II above 700 nm, a region of the visible spectrum that is not absorbed when only chlorophyll a is present in the LHCs.1
Other Notes
Dielectric properties in nematic liquid crystals2; Polarization spectra3; Characterization4,5; Note: anhydrous chlorophylls are very easily enolized, epimerized and allomerized in polar organic solvents (dry).
