isoelectric points given pKa... are they important?

Did anyone see any type of problems like that on their exam? I haven't seen any in the Destroyer nor in Kaplan....I'm wondering.

Or... questions that ask, given a certain pKa and PH, what is the charge of the amino acid?
Or... Tritration curves of Amino Acids?

Am I too worried?

just remember when PI>PH, amino acid has a net positive charge, which means it will be most likely protonated. Also when PH>PI negative charge, deprotonated. There is a question in Destroyer Bio section that might help you.! Lemme know if u have any questions!
Worrying is a part of studying. My test is on Friday and I am trying to relax, but cannot. I am glad to talk to other pepole in the same boat. 🙂
