Conversely, oxygenated blood has a reduced affinity for carbon dioxide.
Histidine residues in hemoglobin can accept protons and act as buffers. This partially explains the observation that some patients with emphysema might have an increase in P a CO 2 partial pressure of arterial dissolved carbon dioxide following administration of supplemental oxygen even if content of CO 2 stays equal.

The majority of carbon dioxide in the blood is in the form of bicarbonate. Oxygenation of blood in the lungs displaces bohd dioxide from hemoglobin which increases the removal of carbon dioxide.
Deoxygenated hemoglobin is a better proton acceptor than the oxygenated form. Please help improve this section by adding citations to reliable sources.
The general equation for the Haldane Effect is: In addition to enhancing removal of carbon dioxide from oxygen-consuming tissues, the Haldane effect promotes dissociation of carbon dioxide from hemoglobin in the presence of oxygen. Nunn’s Applied Respiratory Physiology 5th ed.
Carbon dioxide can bind to amino groups, creating carbamino compounds.
La hemoglobina by Carlos A. Santana on Prezi
Only a very small amount is actually dissolved as carbon dioxide, and the remaining amount of carbon dioxide is bound to hemoglobin.

Scandinavian Journal of Clinical and Laboratory Investigation. Views Read Edit View history. This property is the Haldane effect.
In patients with lung disease, lungs may not be able to increase alveolar ventilation in the face of increased amounts of dissolved CO 2.
Carbaminohaemoglobin is the major contributor to the Haldane effect. In red blood cells, the enzyme carbonic anhydrase catalyzes the conversion of dissolved carbon dioxide to carbonic acidwhich rapidly dissociates to bicarbonate and a free proton:
