WebbHemin is protoporphyrin IX containing a ferric iron (Fe 3+) ion with a coordinating chloride ligand. Chemically, hemin differs from the related heme-compound hematin chiefly in that the coordinating ion is a chloride ion in hemin, whereas the coordinating ion is a hydroxide ion in hematin. [2] The iron ion in haem is ferrous (Fe 2+ ), whereas ... Concomitant with the displacement of two N-H protons, porphyrins bind metal ions in the N4 "pocket". The metal ion usually has a charge of 2+ or 3+. A schematic equation for these syntheses is shown: H2porphyrin + [MLn] → M(porphyrinate)Ln−4 + 4 L + 2 H , where M = metal ion and L = a ligand The insertion of the metal center is slow in the absence of catalysts. In nature, these catalysts (e… WebbErythrocyte zinc protoporphyrin. In iron deficiency and lead poisoning, the enzyme ferrochelatase catalyzes the incorporation of zinc, instead of iron, into protoporphyrin IX, resulting in the formation of zinc protoporphyrin (ZPP).
