WebHemoglobin is the protein that makes blood red. It is composed of four protein chains, two alpha chains and two beta chains, each with a ring-like heme group containing an iron atom. Oxygen binds reversibly to these iron atoms and is transported through blood.
WebSummary. Hemoglobin is the oxygen-carrying pigment present in the red blood cells. It is a tetramer having two alpha chains and two beta chains. It is considered to be made up of two dimers, each dimer including one alpha and one beta chain. One heme group is associated with each polypeptide chain. nys homestead exemptionWebWe will first explore the structure of normal human hemoglobin and then explore the structure of sickle human hemoglobin to reveal how a single amino acid substitution in this protein leads to the development of sickle cell anemia.
