At what pH would the structure be the predominant ionization state? Consider the ionization state of all three of thefunctional groups.The protonated form of the R group of arginine is shown in the structure. The ratio of the charged (protonated) form to thedeprotonated form depends on the pKa of the R group and the pH of the solution.Select all the pH values at which the charged form of the R group would predominate.12.57.413.05.1

The R group of the amino acid Asp contains a carboxyl group with a pKa of 3.7. But the pka of the alpha-carboxyl group in Asp is 1.9. Which of the following. explanations could reasonably account for this difference? 3.7 is the isoelectric pH, which is estimated by averaging the pka of the alpha- carboxyl group with the much higher pKa of the alpha-amino group The R group of Asp also contains an NH2 group, which is less acidic than a carboxylic acid The conjugate base of the alpha-carboxyl could be stabilized by an attractive ionic interaction with the nearby alpha-amino group, which is protonated at low pH Water has better access to the R group than to the alpha-carboxyl group, so it more effectively solvates the charged form of the R group and stabilizes it

Vernon was asked to isolate a storage protein from Saba banana (Musa balbisiana Colla). According to the protocol given by his laboratory instructor, the storage protein must be stored in a 0.750 M citric acid buffer solution pH 6.21. Citric acid is a triprotic acid that follows a dissociation equilibrium shown below: H3CH₂O7 H₂CH₂O7 = z → Ka, = 8.32 x 10-4 Ka₂ = 1.82 x 10-5 HC₂H5O72- C₂H50,³- COMPOUND/SALT H3C6H5O7 NaH₂C6H5O7 Na₂HC6H5O7 Na3C6H5O7 Ž Ka3 = 3.98 x 10-6 Help him prepare the buffer by answering the following questions: 1. Based on the chemical equation above, which species will be the (a) acidic and (b) basic component of the buffer to be prepared? 2. Write the complete equilibrium reaction involved in the buffer system. 3. Write the pertinent chemical equations to illustrate what happens upon the addition of small amounts of (a) strong base and (b) strong acid to the buffer system. 4. Based on your answer in number 1, choose among the salts given in the table below and…
