It says " To be absorbed, dietary iron can be absorbed as part of a protein such as heme protein or must be in its ferrous Fe2 + form.

The reaction catalyzed by complex III is the oxidation of one molecule of ubiquinol and the reduction of two molecules of cytochrome c, a heme protein loosely associated with the mitochondrion.

Oxygen ( O 2 ), nitric oxide ( NO ), carbon monoxide ( CO ) and hydrogen sulfide ( H 2 S ) bind to the iron atom in heme proteins.

Hemoglobin is a prominent example of a heme protein that may be modified by �NO by both pathways : �NO may attach directly to the heme in the nitrosylation reaction, and independently form S-nitrosothiols by S-nitrosation of the thiol moieties.

These are luciferases, which are used by bioluminescent animals and bacteria to produce light, and cytochrome P450, which is a group of heme proteins that hydroxylate a diverse group of compounds, including fatty acids, steroids, and xenobiotics such as phenobarbital.

Although the heme proteins are the most important class of iron-containing proteins, the iron-sulfur proteins are also very important, being involved in electron transfer, which is possible since iron can exist stably in either the + 2 or + 3 oxidation states.

Among Professor Ghosh's edited works are " The Smallest Biomolecules : Diatomics and their Interactions with Heme Proteins " ( Elsevier, 2008 ), a monograph on the subject, and " Letters to a Young Chemist " ( Wiley, 2011 ), a popular science book on careers in chemistry research which is his largest library-collected book.
