And by the presence of an extra fifth ring or isocyclic ring, fixed to the porphyrin head. * In nature, tetrapyrroles possess a structure that is essential for important biological processes. Chloroplasts are plastids that contain a network of membranes embedded into a liquid matrix, and harbor the photosynthetic pigment called chlorophyll. Chlorophylls are very effective photoreceptors because they contain a network of alternating single and double bonds and the orbitals can delocalize the electrons and stabilize the structure. the plant. *Whereas chlorophyll a contains a methyl constituent in its structure, this is replaced by a formyl group in chlorophyll b.
