Use the Henderson-hasselbach equation and solve for the ratio at each pH.
Basic amino acids are histidine, arganine, and lysine.
what are the basic A.A
when do protons dissociate
Acid-base titration is performed, and the amino acid is found to have 3 distinct pKg values: 2.2 for the carboxyl group and 9.2 and 10.7 for the ammonium groups. At
1) pH < 2.2
2) pH = 9.2 -10.7
3) pH > 10.7
What is the most likely net charge of the pictured amino acid?
* Very confused about the protonation and dissociation. PLEASE EXPLAIN STEP BY STEP. Really need to know this pat down for a huge exam tmr!! Thank you!!!!

Isn't is if pH > pKa then it dissociates and if pH < pKa it protonates.
Based off that logic (which was used to explain the answer that I did not understand) how would you go about it?
NH3 protonated is +1
COOH dissociated is -1
etc etc
Thank you for your response, pls follow up!!
