Unformatted text preview: So the possible sequences are: Arg-Phe-Lys-Asn (R-F-K-N) Arg-Trp-Lys-Asn (R-W-K-N) Lys-Phe-Arg-Asn (K-F-R-N) Lys-Trp-Arg-Asn (K-W-R-N) 8. a. sugar alcohols b. It depends on which carbon is selected as carbon 1, since both ends of the molecule have equal priority. If the left-hand carbon is C1, the molecule is D; if the right-hand carbon is C1, the molecule is L. c. D-glucose; sorbitol is reduced at carbon 1 (from aldehyde to alcohol) d. glycerol 9. b 10. a. fatty acid b. myristic acid c. 14:0 (or C-14:0) d. B, C, D, F, G, H e. True f. False g. Yes, pyruvates carboxyl group should have a lower pKa than that of myristic acid, because of the electron-withdrawing inductive effect of the carbonyl oxygen attached to pyruvates carbon 2....
