Iron - Wikipedia

Additionally, this hydrogen bonding results in the tilting of the oxygen molecule, resulting in a Fe–O–O bond angle of around 120° that avoids the formation of Fe–O–Fe or Fe–O 2 –Fe bridges that would lead to electron transfer, the oxidation of Fe 2+ to Fe 3+, and the destruction of hemoglobin.) This results in a movement of all the protein chains that leads to the other subunits of hemoglobin changing …
