Carbaminohemoglobin vs. Carboxyhemoglobin

Carbaminohemoglobinnoun

A compound of haemoglobin and carbon dioxide, one of the forms in which carbon dioxide exists in the blood.

Carbaminohemoglobin

Carbaminohemoglobin (or carbaminohaemoglobin, 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. Twenty-three percent of carbon dioxide is carried in blood this way (70% is converted into bicarbonate by carbonic anhydrase and then carried in plasma, 7% carried as free CO2, dissolved in plasma).

Carboxyhemoglobinnoun

(protein) The stable complex of carbon monoxide with hemoglobin; it prevents the normal complexing with oxygen and thus leads to anoxia

Carboxyhemoglobin

Carboxyhemoglobin, or carboxyhaemoglobin, (symbol COHb or HbCO) is a stable complex of carbon monoxide and hemoglobin (Hb) that forms in red blood cells upon contact with carbon monoxide. Carboxyhemoglobin is often mistaken for the compound formed by the combination of carbon dioxide (carboxyl) and hemoglobin, which is actually carbaminohemoglobin.
