The best biochem professor ever seen. Good job and perfectly explained. What an order and structure, really great work my friend. Thanks so much.

You are really the best! Thank you sooooo much. Your lectures have been really helpful to me.

Just watched all of these amino vids- thanks!

exactly what I was looking for. Perfectly explained. THANK YOU SO MUCH!!!!

At 8:29, did you mean hydrophilic? Your Lectures are very helpful, thank you!

Kayihura Gael , Yeah, he meant Hydrophillic at the end there. He has it written as Hydrophillic on the board. I did a double take as well ahahh. Also love these videos. Very helpful!

I love your lessons! You explain a lot of things!

Your lectures are great!

This is one of the best lecture series I have seen, thank you for doing this!

omg you really are the best... my professors should learn from you

perfect explanation this is what you see when someone loves what theyre doing

Very thankfully, you saved our life!

Thank you very much, well explained

thank you for ur videos, really helpfull

great amazing lectures

so helpful thank you!

Thank you..sir,at the end of the video you meant highly hydrophilic right ?🤔

Yes he actually meant to this...... I mean hydrophilic

your lecture is very helpful for me thanks

Very useful brother thanks for sharing

Thank you!

At the end of the video you say they are very highly "hydrophobic" (min 8:27-8-30). But I think you mean to say hydrophilic. It also says hydrophilic on the whiteboard behind you. just wanted to double check.

I think you are right. Polar molecules (acidic or bazic) are not hydrophobic. This are hydrophilic. Thanks for you and lecturer

By mistake i think he said hydrophobic.. at start he said that due to charge on them they are hydrophilic.

Does glutamate have a delocalised bond? At the 'top' of the molecule on the board

love this, thanks

Anyone got a good mnemonic for the amino acids?

Thank you so much❤️❤️❤️

8:00 The pKa of aspartate is 3.9 at physiological pH (around 7.4).

What happens if you drink essential amino acids with alkaline water?

Thank you 👏🏾👏🏾😉

Thank you

When pH>pka then it'll be deprotonated. So for Histidine with a pka of 6.0 and a pH of 7, why isn't it deprotonated?

Thanks sir ❤️❤️❤️❤️

how can histidine have a positive and negative charge at physiological ph

actually histadine is largely unchaged at about pH7 but the amino group can be protonated depending upon the concentration of H ions in the given environment. but will never be negatively charged.

Good

you mean they're highly Hydrophilic right ?!

can someone pls explain me why when it's positive it represents a basic amino acid and when it's negative it represents an acidic amino acid and in louis defenition of acids and bases it's totally the opposite i mean the acid should be positive and able to have electrons and the base should be negative and able to donate electrons ?

You can have some insights in this video: www.aklectures.com/lecture/introduction-to-amino-acids This is another one that is very straightforward if you are struggling to grasp the concept of net charge on peptides: kzread.info/dash/bejne/mWSIvNCcp86wqLg.html Also, I found some explanation in this video starting at 12:57: kzread.info/dash/bejne/qK1426SOo9O4o8o.html
