Porphyrins (Structure of Porphyrins)
... Porphyrins are cyclic compounds that readily bind metal ions, usually Fe2+, Fe3+. The most prevalent metallopophyrin in human is heme, which consists of one Fe2+ coordinated in the center of tetrapyrrol ring protoporphyrin lX through methenyl bridges. Heme is the prothetic group for hemoglopin, myog ...
