After spending hours trying to actually understand this concept, this truly is without doubt THE BEST video ever made on this topic. You are a life saver!

Thank you so much!

The relationship between pka and pH has been bouncing around my mind for weeks but didn't quite make sense, and it finally clicked with this video! Thank you!!

I am so glad! Thank you so much for watching!

Thanks for this video! I'm currently studying biochemistry (finished 1st course medicine and after 2 months will be 2nd) and this helped me a lot. I got the main point after I watched it only once. I'll wait for the titration. Have a nice day!

I’m confused about Tyrosine, is it polar or non-polar? +Does (Aromatic) necessarily mean non-polar?

Thank you so much for the detailed explanation, really helped me in my studies! At 11:28mins, was there an error in the label for fully protonated? Should it have been no charge instead? The most right hand side label! Thank you!

Hello teacher! I have a question but it is not related to this video. My question is what does steroid sparing mean? Thank you

I've never heard of that concept. It literally means: "without using steroids". Other than that, I have no clue!

[@MedicosisPerfectionalis]

Haha 😂 Sorry!

[@cherrrriii]

I don't get why we need to make the environment's PH equal to the PKa of the drug, why can we just make the drug turn into a non ionized molecule?

[@davesahar]

Are sulfur containing cysteine and methionine hydro Phil or phobic? What about aromatic PhE, tyr, trp or alcohol ser and thr?

[@theresahfosuah3869]

Sulfur-containing cysteine and methionine are hydrophobic amino acids. Aromatic amino acids such as phenylalanine, tyrosine, and tryptophan are also hydrophobic. Serine and threonine are polar amino acids with hydroxyl groups that make them hydrophilic.
