1. All of the following are considered “weak” interactions in proteins, except: A) hydrogen bonds. B) hydrophobic interactions. C) ionic bonds. D) peptide bonds. E) van der Waals forces. 2. In an aqueous solution, protein conformation is determined by two major factors. One is the formation of the maximum number of hydrogen bonds. The other is the: A) formation of the maximum number of hydrophilic interactions. B) maximization of ionic interactions. C) minimization of entropy by the formation of a water solvent shell around the protein. D) placement of hydrophobic amino acid residues within the interior of the protein. E) placement of polar amino acid residues around the exterior of the protein. 3. Which of the following best represents the backbone arrangement of two peptide bonds? A) C α —N—C α —C—C α —N—C α —C B) C α —N—C—C—N—C α C) C—N—C α —C α —C—N D) C α —C—N—C α —C—N E) C α —C α —C—N—C α —C α —C 4. In the α helix the hydrogen bonds: A) are roughly parallel to the axis of the helix. B)
