What “porphyrins” means
Wiktionary · Wikipediaporphyrins
- nounAny of a class of heterocyclic compounds containing pyrrole rings arranged in a square or other similar shape; they are important in biochemistry in a form with a metal atom in the central cavity (hemoglobin with iron, chlorophyll with magnesium, etc.).
Porphyrins are heterocyclic, macrocyclic, organic compounds, composed of four modified pyrrole subunits interconnected at their α carbon atoms via methine bridges, so they are cyclic tetrapyrroles. In vertebrates, an essential member of the porphyrin group is heme, which is a component of hemoproteins, whose functions include carrying oxygen in the bloodstream. In plants, an essential porphyrin derivative is chlorophyll, which is involved in light harvesting and electron transfer in photosynthes
