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...

The lysine side chain has a pKR of about 10. Using the Henderson-Hasselbalch equation, solve for the ratio of [A-] / [HA] that corresponds to the ratio of deprotonated side chains / protonated side chains when pH 10.7. Please calculate the percentage of lysine's side chains that are deprotonated at pH 10.7. Please explain in detail if possible. Thank you.

The charged form of the R-group of histidine (the imidazole ring) is believed to participate in a reaction catalyzed by an enzyme. If you want to test whether or not the hypothesis is correct, you will need to think about the conditions in which the R-group will be charged. To begin, you decide to calculate at pH 7.0 the percent of the molecules that have a charge on the imidazole ring. What percent of the ring is charged? Please, show...

The Henderson-Hasselbalch equation relates the pH of a buffer solution to the pKa of its conjugate acid and the ratio of the concentrations of the conjugate base and acid. The equation is important in laboratory work that makes use of buffered solutions, in industrial processes where pH needs to be controlled, and in medicine, where understanding the Henderson-Hasselbalch equation is critical for the control of blood pH. Part A As a technician in a large pharmaceutical research firm, you need...
