The image depicts the structural formula of a peptide chain, labeled with positions P1, P2, P3, P4, and P5, as well as P1', P2', P3', P4', and P5'. Each segment between the labeled points represents an amino acid residue, characterized by an amide bond between the carbonyl group of one amino acid and the amine group of the next. The backbone of the peptide is shown as a continuous chain of alternating carbon and nitrogen atoms. Key features of the peptide structure include: - **Amide bonds**: Connect the amino acids, forming the backbone of the chain. - **Side chains**: Each amino acid residue has a unique side chain, contributing to the peptide's properties and function. - **Terminal groups**: The chain begins with an amino group (NH₃⁺) and ends with a carboxylate group in the deprotonated form (COO⁻), typical of peptides and proteins. Overall, the diagram illustrates a typical linear peptide structure, useful for understanding the biochemical basis of protein formation and function.

Consider the peptide Asp-Lys-Phe-Glu-Asn-Tyr-Gln-Val-Cys. In a single beaker, you treat this peptide with 2 proteases. One protease cleaves at the N-terminus of aromatic R groups and the other cleaves at the C-terminus of polar, non-ionizable R groups. Following the enzymatic digestion, you want to separate your peptide fragments so that you can identify them. You choose to separate the fragments using an anion exchange column. Beginning at pH=6 you apply your peptide fragments to the column and you gradually decrease the pH of the column stopping the separation when the pH of the column equals 4. Omitting chemical structures, write the amino acid sequence of the peptide fragments that are produced from this digest. Write the order that these fragments will elute from the column (if at all). (Relevant pKa values are: 2.1, 3.8, 4.3, 8.3, 9.6, 10.1, and 10.5)

You are studying how your Lys-Val-Thr tripep de interacts with another pep de, which places an Asp in close proximity to the Lys on your pep de. How would the presence of an Asp side chain affect the pKa of the Lys side chain? Briefly explain your reasoning. (remember pKas are rela ve, pKa=log([H+][A-]/[HA])
