Abnormal Hemoglobin Derivatives| Biochemistry
The following points highlight the three major derivatives of abnormal hemoglobin. The derivatives are: 1. Met-hemoglobin 2. Sulfhemoglobin 3. Carboxyhemoglobin. Derivative # 1. Met-hemoglobin: a. This is an oxidized hemoglobin (ferrous iron is oxidized to ferric iron). Oxygen is in firm combination. b. It is incapable of functioning as an oxygen carrier. Cyanosis usually develops when the concentration of it [...]
