Chlorophyll b is a form of chlorophyll which 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 (sc-214684) is present in the LHCs. Chlorophyll b is a photosynthetic pigment used in the absorption of light energy. Chlorophyl b is involved in photosynthesis and absorbs primarily blue light. Note: May contain stereoisomer chlorophyll b′.
