heme

 [hēm]
the nonprotein, insoluble, iron protoporphyrin constituent of hemoglobin, of various other respiratory pigments, and of many cells, both animal and vegetable. It is an iron compound and constitutes the pigment portion or protein-free part of the hemoglobin molecule, and is responsible for its oxygen-carrying properties.

heme

(hēm),
1. The porphyrin chelate of iron in which the iron is Fe(II) (or Fe2+); the oxygen-carrying, color-furnishing, prosthetic group of hemoglobin.
2. Iron complexed with nonporphyrins but related tetrapyrrole structures (for example, biliverdin heme).
3. Iron chelated with any porphyrin, irrespective of the valence state of the iron atom.
