Each hemoglobin molecule can bind (carry) four oxygen molecules to supply the tissue, in order to prevent hypoxia.
Decreased hemoglobin is seen in cases of anemia (an + emia; literally; no blood)

You said that everything end with "in" is protein. Then why protorpophyrin is among nonprotein?

Chemistry connection . The reason why Fe 2+ is more stable with Oxygen vs Fe 3+ is because of how the electrons fill the orbitals (A levels chem)
Fe : 26th element
Therefore :
Fe = [Ar] 4s2 3d6
Ar represent 18 electrons (18th element)
Fe 3+ = loss 3 electrons, but because s orbitals lower energy than d orbitals, you remove from the 4s first
[Ar] 3d4
Vs
Fe 2+ = 2 electrons lossed = [Ar] 3d5 (loss 2 from 4s)
This half filled 3d subshell is more stable than 3d 4
D subshells can hold 10 electrons, p 6, s 2
So Ferrous is more stable because it has half filled 3d subshell. Vs ferric
Ferric cause fenton rxn :
Fe3+ and O2 ==> trouble aka Reactive oxidative species e.g. OH, O2 2-, H2O2 (which play a active role in many pathologies e.g. G6PD deficiency in hienz body formation)
Result from Methaemaglobineamia which is a ADR to drugs like Sulfanomide (blue baby syndrome) and Benzocaine because they have nitrite deivities. This also promote allergic rxns usually skin related e.g. Steven Johnson Syndrome

idk if still look at comments 3 years later but why does my university not mention protoporphyrin they say heme= porphyrin and iron not protoporphyrin
