- The interactions between the 2 a and 2 b subunits of hemoglobin represent what type of protein structure?Normal Hgb is referred to as HbA and contains 4 subunits, 2 α-globin chains and 2 β-globin chains, arranged as two dimers of αβ. In Sickle Cell Disease, both β-globin chains are altered in the dimers (αβS/αβS). Q3: Which level of structure does the αβ/αβ and αβS/αβS in HbA and HbS describe?How does sickle cell hemoglobin differ from normal hemoglobin at the quaternary level of protein structure (the sum of all the folded protein chains)?

- Avidin exists as a protein complex of around 68 kDa. Research to determine the types of interactions that hold the avidin complex together. Based on your research, which molecular weight would you expect for avidin when treated with beta-mercaptoethanol and run through a native gel? 35 kDa 68 kDa 10 kDa 19 kDaThe hemoglobin in the fetus (HbF) is a structural variant of the hemoglobin in the mother (HbA). HbA is a tetrameric protein complex consisting of two α-globin and two β-globin subunits. HbF is made up of two αglobin and two γ-globin subunits, where the γ-globins are similar to the β-globins but γglobins have lower affinity for 2,3- bisphosphoglycerate or BPG. Studies of oxygen transport in pregnant mammals show that the oxygen-saturation curves between the red blood cells of the fetus and the mother are markedly different. 1. The shape of hemoglobin binding curves is: hyperbolic or sigmoidal 2. a) Based on the binding curves, determine the dissociation constant (Kd) for each hemoglobin complex. (Show correct units.)
