Web26 mrt. 2024 · Hemoglobin is composed of four subunits: two alpha subunits and two beta subunits, each of which contains a heme group and globin chain. The heme group contains an iron atom as ferrous form(Fe 2+) at its core that binds one oxygen molecule, allowing one hemoglobin tetramer to bind four oxygen molecules. [2] WebBeta-globin is a component (subunit) of a larger protein called hemoglobin, which is located inside red blood cells. In adults, hemoglobin consists of four protein subunits: usually two subunits of beta-globin and two subunits of a protein called alpha-globin, which is produced from another gene called HBA.
