Completely lost on what I have to do.

8. You are interested in studying a peptide with the following sequence: H2N-Lys-Ile-Glu-Ala-Glu-Trp-Thr-Pro-Gly-Thr-lle-Asp-Ala-Asn-Phe-Arg-Ala- CO2H The peptide forms a stable -sheet structure and exists in aqueous solution as a dimer at higher concentrations. At more dilute concentrations, the monomer dominates in solution, and you find that it binds readily to membranes, whereas the dimer does not. a) Depict schematically the -sheet structure of the monomer using the one-letter codes for the amino acids as the side chains and clearly indicate the relative orientations of the side chains with respect to the -sheet scaffold (you do not need to draw out the chemical structures of the side chains- just depict their orientations schematically).
