Carboxyhemoglobin (carboxyhaemoglobin BrE) (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. Carboxyhemoglobin terminology emerged when carbon monoxide was known by its historic na… WebJul 27, 2024 · A small percentage (2.5%) of the normal hemoglobin in the adult is hemoglobin A2 (HbA2) which contains δ chains instead of β chains, thus α2δ2.
