1. Calculate the charge on the side chain of the amino acid histidine using the Henderson-Hasselbach equation pH = pKa + log (A/HA+). Use pH =7 and a pKa = 6 and solve to 2 significant figures. 2. Cysteine proteases have unusually reactive cysteine side chains. For one of these enzymes in solution at pH 7 you are able to measure the amount of the deprotonated sulfhydryl (ie, the negatively charged species) as 40% of the total. Calculate the pKa...

In our experiment, we will be using a portion of the phosphate buffer system that is based upon the following equilibrium: H2PO4- HPO42- + H+ pKa = 7.2 In this case, H2PO4- will act as the acid and HPO42- will act as the base. Materials: 1M NaOH: 40.01 g/L of solution 1M HCl: 83 mL conc. HCl/L of solution Potassium phosphate, dibasic, K2HPO4, MW= 174.18 Potassium phosphate, monobasic, KH2PO4 MW= 136.09 **I already preformed this lab, but I struggled a...
