Carbon dioxide binds to hemoglobin
WebJan 17, 2024 · While oxygen binds to the iron content in the heme of hemoglobin, carbon dioxide can bind to the amino acid chains on hemoglobin. When carbon dioxide clings to hemoglobin it forms carbanimohemoglobin. About 10% of carbon dioxide in the human … WebSo hemoglobin is allosterically inhibited by carbon dioxide and by protons. So carbon dioxide can bond to other parts of the hemoglobin-- I don't know the exact spots-- and so can protons. So remember, acidity just means a high concentration of protons. So if you're in an acidic environment, protons can bond.
