- Protein X binds to molecule A. When [A] = 24.5 µmol L-1 at equilibrium, half of X is bound to A and half is not. Calculate the Kd. (Multiply your answer by 1,000,000 before entering. Hint: remember to pay attention to units, and to remember how Kd relates to being half bound.)Which of the following is CORRECT about protein folding? a)The Levinthal paradox demonstrates that proteins must fold randmly b)The Ramachandran plot elucidates the folding rate constant from a first derivative graph c)It is energetically dominated by base pairing interactions d)It probably wouldn’t happen in the presence of significant amounts of organic solvents e_It is always very fast (μs-ms)A protein has a dissociation equilibrium constant equal to 4.0um. What is the concentration of free ligand when the fraction of bound sites is 0.7
- Which of the following statements are correct about the thermodynamics of protein folding (select all that appy)? A. The deltaG for protein folding is negative B. Burial of hydrophobic side provides a positive entropy change that drive protein folding C. The overall entropy change of protein folding is favorable D. Intercations between amino acids provide a large negative deltaH that helps favor the native state. E. The free energy change of protein folding is dependent on the temperatureThe free energy difference going from the unfolded state to the folded state in most proteins is _________. a. small and negative b. small and positive c. large and negative d. large and positive e. highly variableProtein β-sheets are most likely to be found in: a either the interior or exterior of proteins, with no preference for one or the other. b the exterior of proteins, exposed to the aqueous environment. c the interior of proteins, away from the aqueous environment.
- It is observed that as temperature is increased, most protein molecules gofrom their defined, folded state into a random-coil, denatured state thatexposes more hydrophobic surface area than is exposed in the folded state.(a) Given what you have learned so far about ΔH and ΔS, explain why thisis reasonable. (b) Sometimes, however, proteins denature as temperature is decreased.How might this be explained?2. A ligand binds more tightly to the folded state (N) of a protein than to the unfolded state (U). Show that the ligand stabilizes the protein and calculate by how much (ΔΔGfold = ?). Please help me find out deltadelta G fold.The R-group of lysine has an overall positive charge. The R-group of glutamic acid has an overall negative charge. Within the structure of a protein molecule, these two amino acids will: O attract each other O repel each other O form a disulfide bridge O form a pure covalent bond

Contains substantial levels of secondary structure C. Has loose packing of hydrophobic core D. Larger radius of gyration than dentaured state E. Is a more compact state than the native confomationA protein has a clearly defined hydrophobic core; however there is the residue glutamine within the hydrophobic core. How is this residue most likely stabilized (aka ‘made happy’) within this hydrophobic core? a. Hydrophobic interactions b. Interactions with a metal ion c. Hydrogen bonds d. Ionic interactions e.
