- Suh and Savizky studied the thermodynamics of human a - lactalbumin (HLA) unfolding in the absence (apo) or presence of various metal ions (Suh, J. J. and Savizky, R. M., Int. J. Biophys., 2011, 1(1), 1-6). You may assume that the protein starts out in the folded state and becomes denatured when it unfolds. According to the data below, which metal ion results in the greatest enthalpic stabilization of the folded state?

It is observed that as temperature is increased, most protein molecules go from their defined, folded state into a random-coil, denatured state that exposes more hydrophobic surface area than is exposed in the folded state. (a) Given what you have learned so far about AH and AS, explain why this is reasonable. (b) Sometimes, however, proteins denature as temperature is decreased. How might this be explained?In the box below draw the tetrahedral representation of the S enantiomer of the amino acid valine, CH3CH(CH3)CH(NH2)CO,H. • Use the wedge/hash bond tools to indicate stereochemistry where it exists. Do not draw the amino acid in zwitterion form. opy aste ChemDoodle
- Refer to the bar graph below, Explain why e.g. the n→π* interactions contribute more to the overall stabilization of the protein than all the other interactions(C-H-O hydrogen bond,π-π interactions, C5 Hydrogen Bonds, Cation-π interactions, Sulfur-arene interactions, Anion-π interactions, Chalcogen bonds, X-H-π interactions) even though n→π* is the weaker interaction. Explain why they contribute more than EACH bond.Ugfffff I req to u solve for me all ok plzzz accept my RequestThe following sequence is part of a globular protein.
