Can hemoglobin function if it is unfolded
WebAug 10, 2024 · Haemoglobin is a heterotetramer protein composed of four subunits, two α and two β. Its quaternary structure changes with oxygen binding to increase its affinity for oxygen. At the core is a haem molecule, which contains iron and which performs essential gas transport and redox functions. Additionally, haemoglobin functions as a carrier for … WebFeb 1, 2015 · The main function of Mb succeeds only after receiving oxygen from red blood cells (hemoglobin (Hb)), transporting it to the mitochondria of the red muscle cells to produce energy.
