Question

What is carboxyhemoglobin​

Answer 1

Carboxyhemoglobin or carboxyhaemoglobin is a stable complex of carbon monoxide and hemoglobin 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 and hemoglobin, which is actually carbaminohemoglobin

${ \tt{ \red { \underline{ \underline {\huge{ Answer:}}}}}}$

Carboxyhemoglobin (COHb), which normally comprises less than 1-2 % of total hemoglobin, is the product of reaction between carbon monoxide and hemoglobin. Carbon monoxide is produced endogenously but is also a common environmental pollutant; both sources contribute to the amount of COHb in blood.
