1) Draw the structures of D-lysine and L-lysine and assign R/S configuration (showing your workings). 2) Draw the predominant ionisation forms of the free amino acid lysine, at pH 1.0, 8.0, and 11.0. pKa values: 2.2 (-COOH), 9.0 (α-NH3+), 10.5 (side-chain). 3) Calculate (showing your workings) the % of the different ionized species that are present in a 1.00 M solution of L-proline at pH = 10.0. pKa values: 1.95 (- COOH), 10.64 (α-NH3*). 4) a) Draw the tripeptide Tyr-Pro-Lys once with a trans peptide bond between Tyr and Pro and once with a cis peptide bond between Tyr and Pro. b) The electrospray ionization mass spectrum (ESI-MS) of the tripeptide you designed in part (a) shows peaks indicative of mono-protonation and di- protonation of the tripeptide. At what values of m/z would these peaks be expected (no fragmentation)? Briefly explain your answer (showing your workings). 5) How could the sequence of Ala-Met-Thr be distinguished from that of Thr-Ala- Met by tandem ESI-MS-MS?…
