Each hemoglobin molecule
WebDec 10, 2024 · Hemoglobin is a large molecule made up of proteins and iron. It consists of four folded chains of a protein called globin , designated alpha 1 and 2, and beta 1 and 2 (Figure 3a). Each of these globin molecules is bound to a red pigment molecule called heme , which contains an ion of iron (Fe 2+ ) (Figure 3b). WebHemoglobin and myoglobin are heterotetramers. Each iron atom can form six coordination bonds. Two of these bonds are formed between iron and oxygen. Both hemoglobin and …
