Proteins become real in your students' hands as they fold 3 Mini-Toober β-globin fragments and discover primary, secondary and tertiary structure in this model. Maps guide students in marking the levels of structure onto 3 Mini-Toober fragments before folding each into its 3D shape. These three fragments are then assembled to form the completed structure. Connectors simulating hydrogen bonds help to stabilize the structure, and selected sidechains are added to demonstrate salt bridges, heme binding, and the site of the mutation leading to sickle cell anemia. Oxygen binding at the heme group can also be demonstrated with the completed model.
