One-Letter Code Translation: Convert the given hexapeptide sequence into its one-letter amino acid code. 2. Possible Charge States: List all possible charge states that this hexapeptide can have, considering the pKa values of ionizable groups. 3. Predominant Form at pH 3.2: Determine the predominant charge state of this peptide at a pH of 3.2. Clearly indicate which functional groups are protonated or deprotonated. 4. Isoelectric Point (pI) Calculation: Calculate the isoelectric point (pI) of this hexapeptide. Show all necessary steps and justifications for selecting relevant pKa values. 5. Strongest R-Group Interactions at pH 7.5: For each amino acid R-group, identify the strongest type of interaction it can participate in at physio- logical pH (7.5). Consider hydrogen bonding, hydrophobic interactions, ionic interactions, and disulfide bonds. 6. Amino Acid Classification: Classify each amino acid in the sequence as one of the following: 鈥?Nonpolar 鈥?Polar (uncharged) 鈥?Polar (negatively charged) 鈥?Polar (positively charged) 鈥?Aromatic 7. Secondary Structure Propensity: Predict whether this peptide is more likely to be found in an alpha-helix or beta-sheet. Compare the propensity scores of each amino acid and discuss the influence of any known secondary structure breakers. 1
