Calculate the concentration of the isoelectric form of lysine if the pH of the solution is 9.4000000000 and the total concentration of Lysine is 78.9000000000 μM.
Calculate the concentration of the isoelectric form of lysine if the pH of the solution is...
10-20. Find the pH and the concentration of each species of lysine in a solution of 0.010 O M lysine · HCl, lysine monohydrochloride. The notation "lysine · HCl” refers to a neutral lysine molecule that has taken on one extra proton by addition of one mole of HCl. A more meaning- ful notation shows the salt (lysineH*)(C1) formed in the reaction.
