Which of the following is true of secondary structure in protein folding? Pick ALL that apply. A. It involves hydrogen bonding. B. It involves the side chains. C. It involves hydrophobic interactions. D. It results in alpha helicies with the side chains hidden inside the helix. E. It results in beta-pleated sheets with side chains sticking out of the plain of the sheet. F. It involves the peptide backbone.
How does the hydrophobic effect influence protein folding? In an aqueous environment, nonpolar portions of the molecule A) are generally exposed to solvent and interact effectively with water. B) interact with polar portions in the interior of the protein. C) can be placed on the surface of the molecule only if hydrogen bonded to water. D) are found in the interior of the protein, away from water, which preserves the entropy of water in solution.
25) What maintains the secondary structure of a protein? a) hydrophobic interactions b) hydrogen bonds between the R groups c) peptide bonds d) disulfide bonds e) hydrogen bonds between the amino group of one peptide bond and the carboxyl group of another peptide bond

You need to denature a heterodimeric protein that uses both ionic interactions and hydrophobic forces to hold the dimers together. Each subunit has 2 disulfide bonds that hold their 3 structures together. One subunit is primarily composed of P-Sheets while the other has multiple helix-strand-helix motifs. The subunit with the helix-strand-helix also has a number of polar and charged residues on its surface. What would you do to denature this protein and which NCI would be...
1) In the mechanism for peptide bond formation, what acts as the initial electrophile? 2) Consider a globular protein forms a stable 3D (tertiary) structure, where the entropic cost of folding is: -1769 J/K*mol (this would be the sum of the hydrophobic effect and the entropy of the protein). If the protein folds entirely into an alpha helix and the only sidechain interactions in tertiary structure are side chain hydrogen bonds - how many hydrogen bonds are required for the...

1) Indicate why alpha helices and beta sheets help "bury" hydrophobic amino acids in the interior of a folded polypeptide in an aqueous environment. 2) Explain what is meant by the statement "Protein folding is driven by hydrophobic interactions" and under what conditions this is true.
