Carbaminohemoglobin (carbaminohaemoglobin BrE) (CO 2 Hb, also known as carbhemoglobin and carbohemoglobin) is a compound of hemoglobin and carbon dioxide, and is one of the forms in which carbon dioxide exists in the blood. [1]
The sugar-carbamino is formed through a C-glycosidic linkage with the amino acid side chain via various linkers. The synthesis involves introducing annulation to appropriate amino acid residues to rigidify glycopeptides, followed by Diels-Alder cycloadditions to fuse cyclic α- and β-amino acids to the sugar moiety.
Carboxyhemoglobin is often mistaken for the compound formed by the combination of carbon dioxide and hemoglobin, which is actually carbaminohemoglobin. Carboxyhemoglobin terminology emerged when carbon monoxide was known by its historic name, "carbonic oxide", and evolved through Germanic and British English etymological influences; the ...
This amount of carbaminohemoglobin formed is inversely proportional to the amount of oxygen attached to hemoglobin. Thus, at lower oxygen saturation, more carbaminohemoglobin is formed. These dynamics explain the relative difference in hemoglobin's affinity for carbon dioxide depending on oxygen levels known as the Haldane effect.
Even though carbon dioxide is carried by hemoglobin, it does not compete with oxygen for the iron-binding positions but is bound to the amine groups of the protein chains attached to the heme groups. The iron ion may be either in the ferrous Fe 2+ or in the ferric Fe 3+ state, but ferrihemoglobin (methemoglobin) (Fe 3+) cannot bind oxygen. [50]

Carbon dioxide (CO 2) is produced in tissues as a byproduct of normal aerobic metabolism.It dissolves in the solution of blood plasma and into red blood cells (RBC), where carbonic anhydrase catalyzes its hydration to carbonic acid (H 2 CO 3).
