... Carbon monoxide, an odorless gas, binds to hemoglobin to form CO-hemoglobin. Crystals of CO-hemoglobin are isomorphous with those of oxyhemoglobin, which suggests that COHb has the same conformation as oxyhemoglobin. Each heme in Hb can bind one CO molecule, but O2 and CO cannot simultaneously bind ...
