Explanation:
Hemoglobin is a blood hemoprotein, with a molecular mass of 64,000 g / mol (64 kDa), of a characteristic red color, which transports the dioxygen (commonly called oxygen), O2, from the respiratory organs to the tissues, the dioxide of carbon, CO2, from the tissues to the lungs that eliminate it and also participates in the regulation of blood pH, in vertebrates and some invertebrates.
Hemoglobin is a quaternary structure protein, which consists of four subunits. This protein is part of the hemoprotein family, since it has 1 heme group in each subunit
Hemoglobin is a tetrameric protein, which consists of four polypeptide chains with different primary structures. ... Each hemoglobin polypeptide chain is attached to a heme group to form a subunit. The four subunits of hemoglobin in its quaternary structure form a tetrahedron.
