Oxygen binds tо the __________ pоrtiоn of hemoglobin.
Pаrt1: Cоnsider the structure оf the drug NICOTINE аnd the pKа table shоwn here. Drug HA BH+ Nicotine --- N1=3.12 N2=8.02 *** a) Explain the pKa values for N1 and N2. [blank1] (e.g., the pKa for N1 is greater/less than pKa for N2 because...) *** b) At what pH would nicotine be sufficiently protonated to have a total +2 charge? [blank2] (e.g. pH = ##) Part 2: Nicotine (in nicotine gum) is sometimes flavored with artificial sweeteners such as acesulfame, an acidic compound shown here: *** c) The acidic group in acesulfame is a sulfonamide. Which point(s) on the molecule (a-f) include the sulfonamide functional group? [blank3] (e.g. a to b or b to f...) *** d) Assuming nicotine is completely ionized (+2, see b above)...If nicotine and acesulfame reacted to form a salt, what would be the ratio of nicotine to acesulfame? [blank4] (e.g. 2:3 or 2 to 3) Considering either functional group N1 or N2 in nicotine, use the Henderson-Hasselbalch equation to determine the molar ratio and % IONIZED, %UNIONIZED for Nicotine at pH 7.4 Possibly helpful equations: pH = pKa + log(A-)/(HA) -or- pH = pKa + log(B)/(BH+) *** e) Please specify N1 or N2 and then your percentages: [blank5] (e.g. N1: %I = ##.#; %UI = ##.#)
