Only a very small amount is actually dissolved as carbon dioxide, and the remaining amount of carbon dioxide is bound to hemoglobin.
This section does not cite any sources. Amino groups are available for binding at the N-terminals and at side-chains of arginine and lysine residues in haemoglobin.

This partially edecto 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.
Conversely, oxygenated blood has a reduced affinity for carbon dioxide. In addition to enhancing removal of carbon dioxide from oxygen-consuming tissues, the Efecgo effect promotes dissociation of carbon dioxide from hemoglobin in the presence of oxygen. Deoxygenated hemoglobin is a better proton acceptor than the oxygenated form.
Haldane effect – Wikipedia
This property is the Haldane effect. Oxygenation of blood in the lungs displaces carbon dioxide from laa which increases the removal of carbon dioxide. 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.

The Haldane effect is a property of hemoglobin first described by John Scott Haldane. Hematology Hemoproteins Respiratory physiology.
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: The majority of carbon dioxide in the blood is in the form of bicarbonate.
The general equation for the Haldane Effect is: Articles needing additional references from June All articles needing additional references.

This page was last edited on 6 Octoberat Carbon dioxide can bind to amino groups, creating carbamino hemolobina. Histidine residues in hemoglobin can accept protons and act as buffers.
In patients with lung disease, lungs may not be able to increase alveolar ventilation in the face of increased amounts of dissolved CO 2. Unsourced material may be challenged and removed. By using this site, you agree to the Terms of Use and Hemoglbina Policy.
