WebMay 17, 2024 · Hemoglobin. Hemoglobin is a large molecule made up of proteins and iron. It consists of four folded chains of a protein called globin, designated alpha chain 1 and 2, and beta chain 1 and 2.Each of these globin molecules is bound to a red pigment molecule called heme, which contains an ion of iron (Fe 2+) (Figure … WebEach globin chain is associated with one heme group, containing one atom of iron. Each of the four iron atoms can bind loosely with one molecule (two atoms) of oxygen. Thus, each hemoglobin molecule can transport eight oxygen atoms. Suggest Corrections.
