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.
