55. If the amino acid proline is present in a polypeptide chain. What will be its most likely effect if the amino acid chain formed an alpha-helix? A. It will inhibit the formation of hydrogen bonds with a regular pattern. B. It will cause steric hindrance because it has a bulky R group. C. Its prosthetic group is too small that it allows for excessive movement of the protein structure. D. It stabilizes the entire protein structure. E. All options are actually valid. 56. What will be the most likely effect if the amino acids Glu and Asp are made to interact with one another in close proximity upon folding of a polypeptide chain that folded into an alpha-helix? A. It will inhibit the formation of hydrogen bonds with a regular pattern. B. It will cause steric hindrance because it has a bulky R group. C. It will destabilize the structure because the negative charges will repel each other. D. It will further stabilize the structure because their opposite charges will induce a high-energy bond.
