Deoxygenated hemoglobin is hemogloibna better proton acceptor than the oxygenated form. Only a very small amount is actually dissolved as carbon dioxide, and the remaining amount of carbon dioxide is bound to hemoglobin. Please help improve this section by adding citations to reliable sources.

Amino groups are available for binding at the N-terminals and at bohrr of arginine and lysine residues in haemoglobin. The Haldane effect is a property of hemoglobin first described by John Scott Haldane. The majority of carbon dioxide in the blood is in the form of bicarbonate.
In the oxygen-rich capillaries of the lung, this property causes the displacement of carbon dioxide to plasma as low-oxygen blood enters the alveolus and is vital for alveolar gas exchange. In patients with lung disease, lungs may not be able to increase alveolar ventilation in the face of increased amounts of dissolved CO 2.
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.

This property is the Haldane effect. 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. Histidine residues in hemoglobin can accept protons and act as buffers. Views Read Edit View history.
Oxygenation of blood in the lungs displaces carbon dioxide from hemoglobin which increases the removal of carbon dioxide. From Wikipedia, the free encyclopedia.

Conversely, oxygenated blood has a reduced affinity for carbon dioxide. Carbaminohaemoglobin is the major contributor to the Haldane effect.
