29. In the following polypeptide, where might bends or turns occur? Where might intrachain disulfide cross-linkages be formed? Phe-Ala-His-Cys-Thr-Trp-Gly-Phe-Pro-Glu-Ser-Ala-Met-A rg-Trp-Glu-Ala-Asn-Asp-Gly- Pro-Met-Glu-Ala-Phe-Cys-His-Arg-

28. You wish to determine the sequence of a short peptide. Cleavage with trypsin yields three smaller peptides with the sequences Leu-Glu, Gly-Tyr-Asn-Arg, and Gln-Ala-Phe-Val-Lys. Cleavage with chymotrypsin yields three peptides with the sequences Gln-Ala-Phe, Asn-Arg-Leu-Glu, and Val-Lys-Gly-Ty. What is the sequence of the intact peptide?
