Superclasses: a macrocyclea chlorin

Chlorophyll is a green pigment found in most plants, algae, and cyanobacteria. The name is derived from Greek (chloros "green" and phyllon "leaf". Chlorophyll absorbs light strongly in the blue and red spectra and has a strong green color. Chlorophylls play a crucial role in photosynthesis, both in the antennae and in the reaction centers. By far most of the chlorophylls are found in the antennae, where they absorb light and transfer that light energy by resonance energy transfer to the reaction center. Some of the cholorophylls (known as P700 and P680) are part of the photosystems reaction centers, where they perform the charge separation reaction, sending electrons to a transfer chain that ultimately results in the reduction of NADP+ to NADPH.
