1. (7 points) The average blood concentration of ticarbenate in aduts is 25 mmoil and the average lovel of dissolved carbonis acid (Kk=6.77) is 10 menoil. Both blood concontrations in an unresponsive, heavily alcohol thitoxicaled petient wore mepsured to be 15 mmoll. bicarbonate and 9 mmoll carbonic acid. a) Determine the pH of the patients blood (show calculations) and state if acute acidosis of alkolosis is indicated. b) Would increasing the pump rate of the ventilator help solving the patients situation? Explain your answer on basis of a sulable equation. c) Name two potential chronic causes for the patient's condition (excluding the acute. alcohol overdose). 2. (10 points) Which one of the below tetrapeptides: A B c) D. E Asp-His-Glu-Ala Asp-Trp-Tyr-Gly Gly-Gly-Pro-Arg Tyr-Lys-Met-lle Leu-Val-Phe-Ala D. (a) has a neutral charge at pH 7? (b) will yield DNP-glycine when reacted with 1-fluoro-2,4-dinitrobenzene and hydrolyze in acid? (c) contains the largest number of nonpolar R groups? (d) contains the most acidic amino acids? (e) will have the greatest light absorbance at 280nm ? (f) will most likely form a -tum if found in a properly folded protein? (g) can form the most hydrogen bonds with the same peptide neighbor? (h) has the lowest solubility in water (pH7) ? Palculate the approximate pl of peptide E. Show your calculation
