Hemoglobin f structure

WebBoth fetal and adult hemoglobin are composed of four subunits: both have two identical alpha subunits, but in fetal hemoglobin, the two beta subunits found in adult hemoglobin are replaced with two gamma subunits (shown here from PDB entries 4hhb and 1fdh ). These gamma subunits give fetal hemoglobin its increased affinity for oxygen. WebStructure and function. Hemoglobin A (HbA) is the most common adult form of hemoglobin and exists as a tetramer containing two alpha subunits and two beta subunits (α2β2). Each subunit contains a heme group that diatomic oxygen (O 2) molecules can bind to. In addition to oxygen, subunit assembly and quaternary structure are known to play …
