(a)
Interpretation:
The a-keratin and hemoglobin should be compared on the basis of secondary structure.
Concept Introduction:
The primary structure of a protein is the sequence of amino acids. The a-helix and β-sheet structures are the secondary structures. Similarly, tertiary and quaternary structures also have certain weak intermolecular forces. These structures have different intermolecular forces between peptide chains like hydrogen bonds, S-S bonds, etc. which get altered after heating or in the presence of certain chemicals. Hence, these structures get changed during the denaturation of the protein.
(b)
Interpretation:
The a-keratin and hemoglobin should be compared on the basis of water solubility.

Hint: Let the π orbitals be equal to xf and yf, where f is a function that depends only on the distance from the internuclear axis.arrow_forward(a) Verify that the lattice energies of the alkali metal iodides are inversely proportional to the distances between the ions in MI (M = alkali metal) by plotting the lattice energies given below against the internuclear distances dMI. Is the correlation good? Would a better fit be obtained by plotting the lattice energies as a function of (1 — d*/d)/d, as theoretically suggested, with d* = 34.5 pm? You must use a standard graphing program to plot the graph. It generates an equation for the line and calculates a correlation coefficient. (b) From the graph obtained in (a), estimate the lattice energy of silver iodide. (c) Compare the results of (b) with the experimental value of 886 kJ/mol. If they do not agree, explain the deviation.arrow_forwardCan I please get help with #3 & 4? Thanks you so much!arrow_forwardarrow_back_iosSEE MORE QUESTIONSarrow_forward_ios
