Web14 okt. 2024 · Haemoglobin (Hb) is the major macromolecular fraction of red blood cells (RBCs). In solution, the Hb protein is a homotetramer that consists of two α- and two β-chains bearing in total four haem groups [ 1 ]. Only higher vertebrates produce highly specialized RBCs for oxygen transport in their cardiovascular circulations. WebState the purpose of hemoglobin in RBCs. Red blood cells contain many hemoglobin molecules. Each hemoglobin contains four iron- containing heme groups, which allows the hemoglobin to bind up to four O 2 or CO 2. Word Bank: hemoglobin, iron.
