WebHaemoglobin (Hb) is a type of globular protein present in red blood cells (RBCs), which transports oxygen in our body through blood. It is a tetrameric protein and contains the heme prosthetic group attached to each subunit. It is a respiratory pigment and helps in transporting oxygen as oxyhaemoglobin from the lungs to different parts of the body. WebHemoglobin The amount of Hb F present is a function of the number of reticulocytes that contain Hb F, the extent of selective survival of Hb F–containing reticulocytes that become mature Hb F–containing erythrocytes (F cells), and the amount of Hb F per F cell.
