Shоwn belоw is the structure оf the аmino аcid, tyrosine. Pаrt A) 5 points How many acid-base equilibria do I have to consider in tyrosine? Use the table below to find out. Part B) 25 points The pKa values of tyrosine are 2.2, 9.11 and 10.07. Indicate what equilibria these pKa represent. Indicate the correct overall charge of each species. Part C) 10 points Indicate quantitatively which equilibria can be neglected in your calculation of contributions to total tyrosine concentration. Part D) 20 points Calculate the equilibrium concentrations of all molecular species present in a tyrosine solution at pH 9.5 that you obtained by mixing NaOH and tyrosine to give a solution that is 0.1 M in total concentration of this amino acid, tyrosine. Please do not fill in anything in the box provided below but instead upload your written answer as per instructions.
