A porphyrin head of chlorophyll typically includes four pyrrole rings fixed to the coordinated central metal, and thus called as “Tetrapyrroles”. 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.

What enables eukaryotes to perform more specialized functions than prokaryotes do? The porphyrin ring (head) is a flat, square structure containing four smaller rings (I-IV), each possessing a nitrogen atom which can bond with magnesium atom. complement system. The chlorophyll molecule consists of a central magnesium atom surrounded by a nitrogen-containing structure called a porphyrin ring; attached to the ring is a long carbon–hydrogen side chain, known as a phytol chain.
