Effect of pH and pKa on Amino Acid Structure

[@JigmeSwag]

Wish I saw this video when I took Biochem. Now prepping for MCAT and this makes sense now. Ready to answer AA questions.

[@Kencan254]

Well explained. The video clears the cloud of mystery and confusion on the topic. Thanks.

[@cowboybiochemistry1081]

It can be mysterious...glad this video helped you!

If I get a 90 on this biochem exam im about to take, i will mail you a cake

[@nobody4985]

Finally I understood, thank you so much sir !

[@YvonneMutabazi-ch3ct]

Thank you very much 🙏 I was having challenges but now all good

[@sarikasingh6060]

Very helpful.... Thank you so much.... The explanation wouldn't have been more lucid..... :)

[@abdullahshahid8996]

So helpful highly recommend

[@oscarmeneses2434]

Thank you sir!. well explained.

This video helped me so much! Thank you thank you thank you!!!!

finally, i understand Thank you!

I’m curious how exactly pH changes the weaker force of hydrogen bonding. This is a partial charge to do with the distribution of electrons within a molecule rather than it being protonated or not. So how can pH affect that? Many texts simply state that hydrogen bonds are affected by pH without clearly explaining how.

This means a lot. Thank you

[@wheresthecake375]

really helpful thank you

What about if ph = 7 for Histidine ? I did this exactly and everything was wrong.

[@mrscherryhuggypoinks9438]

For the last examples, shouldn’t NH3 become NH4 since it’s protonated?

[@wiljamvandijk152]

no it is already in it's acid form

[@pettytatinyuy4548]

I think it's original form is NH2 and when protonated it becomes NH3+

[@seantrew9713]

You are a god

[@darin3762]

Very good. Can I have extra credit?

[@asandiswashange8987]

Thank you so much!!!

[@jackjyoung]

Thank you

[@mizzannie001]

thank you!!!!!!!!!!!!!!!!

[@nasi7399]

if its is protonated it should be NH4 + AT PH 2 because it was NH3 which means gain another H. nice vidio anyway

[@marind10]

No, its already in it's acid form.

thank you
