Detailed explanation of titration curve of histidine
In this video, I walk through how to read a titration curve for an amino acid and the information we can extract from it such as pKa values, pI values, and predominant forms of the amino acid at various pH values.

thank you SO much for posting this!!!
This was such a helpful video, thank you so much!
Awesome thank you for posting this!!!
Clear explanation, Thank you!!
Really neat and helpful video 😍
Thank you, how do you do this with H+.
Thanks you
Does this represent a good buffer, and why?
ThankyouThankyouThankyouThankyouThankyou!!!!
Why is the curve...curve like that?
thank you so much. Is there a way to know the percentage of unprotonated structures at certain ph?

Yup! You can do this a couple ways, but the core of it lies in using the Henderson Hasselbach equation. If you know the log term (moles of base/moles of acid), then you can determine the percentage of each. For example, if I solved and got as the log term --> 0.1. Then I know that the ratio of base to acid is 0.1. In other words, there is 0.1 mol of base for every 1 mole of acid. The total is 1.1 moles. So, 0.1 / 1.1 = 9.0% base. So, if you have a pH, then you can find that log term (also need to use the pKa for the correct acid/base pair).
Which the video could be more clear
