Omg these lectures are flawless I literally wanna cry from happiness. it’s been 8 years since they have been published but the best lectures I have ever watched
Its been 4 years. I dont know what college u went, but this comment represents me now. I was overwhelmed for understand nothing in class. Thanks my lecturer recommend this vid afterwards.
These Videos were post/published almost 2 years ago and am here enjoying every part of em...Biochemistry seemed so tough but now i feel like all i needed was to take a glimpse at these videos and thats was it...Thank you AK LECTURE your knowledge via is really more than helpful..
Thanks so much for all your lectures!!!!you should come to our university!!!you make biochemistry so easy and i appreciate your hard work and the way you structure your lectures in a way that everyone can understand!!!!!!!keep up the good work!!!
I feel like you just saved me so many hours of studying the long poorly worded book to understand what you just taught me in 10 minutes (thanks to 1.5 speed haha). You are awesome!!!!!
Am grateful for these free services.Biochemistry is now very easy for me. God bless and I hope to make a reasonable donation of this good course someday.Thanks and more strength
You go so much more in depth with these topics than my teacher, that I dont have to keep constantly asking myself "why does this happen" or "we seem a bit short on notes." Thanks for this :)
i listen ur lecture it help me a lot in my exams ur way of teactng is awesome ...ii enjoy ur lecture it deeply penetrate in my mind thnx AK LECTUREs :)
The efforts and the way of teaching is so frickin sick, prof! I have accepted the fact that most of the teachers have knowledge but they cannot convey it properly Except some who are god gifted like you❤
Your videos are really good. I understand everything better, when you explain it, even though I am from Austria and a native german speaker. You should teach at my University of Pharmacy :-)
I'm confused, question: "The peptide bonds have a double bond character" but I noticed all the drawings of the C-N bond appear as a single bond, is this "character" you're speaking of indicatory of a resonance occuring between the C=O double bond and the C-N bond? Thus causing it to have another double bond character as to not freely rotate? Tyvm! Excellent...really excellent lectures btw. Liked & subscribed.
love you lectures so much. you make things simple and easy to understand. i was wondering what references you use for this topic? hope i get a reply from you :)
Is there a list of amino acid sequences organized into the two main categories: 1. Alpha helix 2. Beta-pleated sheet? I recently made a program that randomly generates an amino acid sequence. The program stops when a stop codon is generated. That is, there's a 3/64 the program will stop after each amino acid is generated. However, I'm unable to find the necessary information to create a program of perfect information for the secondary structure.
A question, if the formation of a-helices and b-sheets depend exclusively on the H-bonds of the polypeptide backbone, and not on the side chains (which are variable), what does determine if an a-helix or b-sheet will take place? Because the N-H and C=O of the backbone will always be the same! You are a great teacher, thanks!
The amino acid residues within the polypeptide chain determine what conformation will occur. Proline, glycine, and charges amino residues disrupt the alpha helix so if they're found in a protein, that section will likely be a beta turn. Small hydrophobic residues like alanine and leucine, on the other hand, are perfect for forming alpha helices.
Is the beta sheet consist of more than one peptide/polypeptide chain and beta turns connected them to result in a one polypeptide chain? or it is one polypeptide chain and the side that turns it called beta turns?
h ak million times of sorry! i didn't let you know after my exam and i saw your message just now! of course it did well. and just because of you:) i recommend your videos to every of my friends and will keep recommending... billions of thanks again...
No se como hace, pero hace que in tema que parecia inabordable, parezca fácil. Creia que si no tenía una computadora de última generación, jamás lo iba a poder entender... Congratulations!!!
Good lecture bro, i have a question. can you show right handed and left handed cross over connection in parallel beta sheet. i have a doubt in understanding why the images in books look opposite ( i mean the right handed one looks left hand to me, I think i am interpreting those images wrongly)
Can you tell me why there is a decimal number of amino acid residues 3.6 in alpha helix and how can be an amino acid residue be a decimal number and not a whole number?
"and what that means is..."
so beautiful.
thank you.
the amount of respect I have for just being able to draw out alpha helix, with detail and legibility. its beyond me
For non-English speakers, what could be a synonym for rad-like structure?
this is so helpful. thank u
Omg these lectures are flawless I literally wanna cry from happiness. it’s been 8 years since they have been published but the best lectures I have ever watched
Your videos are sick bro. Making this biochem significantly easier... summing 2 hour conversations into 14 mins. Thanks
Its been 4 years. I dont know what college u went, but this comment represents me now. I was overwhelmed for understand nothing in class. Thanks my lecturer recommend this vid afterwards.
@@vanessamumu1968 its been another year. This video = still relevant
I have been a loyal lover of the lectures, 3 years now
still relevant, and the best..
Still
These Videos were post/published almost 2 years ago and am here enjoying every part of em...Biochemistry seemed so tough but now i feel like all i needed was to take a glimpse at these videos and thats was it...Thank you AK LECTURE your knowledge via is really more than helpful..
Some more additional information: β-turns often consist of Glycine which provides flexibility and Proline, which provides steric constraints.
"wow, this is a H, not a N" 😂😂😂
13:26
I swear this finally makes sense! thanks so much!!!!
6 years ago they were posted and still they are mesmerising.....you are god gifted mateeeee❤
Your videos are absolutely amazing !! thank you so much for all of them
Thanks so much for all your lectures!!!!you should come to our university!!!you make biochemistry so easy and i appreciate your hard work and the way you structure your lectures in a way that everyone can understand!!!!!!!keep up the good work!!!
Thanks so much for making everything easier to understand!
You r one of the best teacher for me to come across . A great job and thus a great apreciation
Bt where r u now ?
No more uploads !?
You're excellent, 4 years back I used to learn modern physics from ak lectures
Now as a medical student learning biochem
You are so versatile
I feel like you just saved me so many hours of studying the long poorly worded book to understand what you just taught me in 10 minutes (thanks to 1.5 speed haha). You are awesome!!!!!
this video was published when i was in 5th grade, and now, im a 1st yr college student who you just saved. tysmm
2022 and you taught me more than my prof in university. thank u so much !!
Am grateful for these free services.Biochemistry is now very easy for me. God bless and I hope to make a reasonable donation of this good course someday.Thanks and more strength
Your explanation unbelievable!!
The best videos I have ever watched. Thank you for these wonderful explanations. Could you please explain omega loop as well?
Kind Regards
Nicely explained men . You have explained the basic compositions of structure . It's good for me
Thank you a lot ...the way you explain even a new born baby can even understand
Sir, Thank you so much!! I have my biochemistry exam tomorrow and I rely on your videos to do well on it.
You go so much more in depth with these topics than my teacher, that I dont have to keep constantly asking myself "why does this happen" or "we seem a bit short on notes."
Thanks for this :)
i listen ur lecture it help me a lot in my exams ur way of teactng is awesome ...ii enjoy ur lecture it deeply penetrate in my mind thnx AK LECTUREs :)
That's one hell of a drawing. Huge props for that Helix
i Don't know how i express my greatfullness. thanks a lot sir.
kudos!!! Thank you so much for explaining everything in such detail
very good video thanks for the amount of detail and effort!
13:26 that wow described my whole process of learning from this video 😂 Thank you soo much 💕
clear explanation starting from basics thank you !
Very well explained sir. Clear explanation. You are a true inspiration....
You make it too easy! thank you thank you and one more thank you
you explain in such a nice way that it makes me
so easy to understand
Amazing thank you thank you from the bottom of my brain!
The efforts and the way of teaching is so frickin sick, prof!

you are awesome, so easy to understand
Give that man a cookie
Just awesome . Thank you a lot..
Amazing lectures!
beautiful explanation!
Your explanation is something beyoooonnnnddd!!!!
love your videos!
thank you a lot.. its really helpful....
excellent review videos for MCAT biochem, thank you
just22ish thats wonderful! :-) best of luck with the exam! definitely a mental marathon.
You r doing a great job
Your videos are really good. I understand everything better, when you explain it, even though I am from Austria and a native german speaker. You should teach at my University of Pharmacy :-)
Спасибо! Довольно доступно все объяснено)
you are an excellent teacher
Helpful stuff. But you didn't talk about omega loops :(
THANK YOU!
You are amazing sir,hats-off
Thank you!
Thank you so much. Made more sense than my lecturer. I'm a med student.......
Thank you thank you thank you !!!
Reallly helpful,Thanks

Dianne Galang good in lippincott biochem
Extraordinary teaching 🤩
Awesome lecture 👌
Thank you sir,it was so helpful for me 🤗
You’re amazing!
The R groups on the anti parallel lower chain have their chirality reversed (wedges should be dashes, and vice versa).
Thank you so much, you're a lifesaver!
you're welcome!
Thanks so much!!!
Thank you for the greattt explanation..
The notes on the board are so crisp I didn't even need to watch the whole video to understand!
you are so good like really good lmaooo this is insane! im taking my money back from my teacher because i only learn from you
Awesome! Thanks!
np!
good work thanks

great! but i just want to know what is the difference between (loop region - beta turns - disordered region( ??
A left-handed α-helix results in steric hindrance between the side chains and the C=O groups from the amide/peptide bonds.
Thank you so much
Literally u r awesome sir🤩🤩
May god bless u always 🙌🙌🙌
U explain each and every concept very smoothly 🤍🤍
you are just woww evenn... keep it up, do a series on organic chemistry maybe
Perfect 👍🏻
fantastic
Thank you
Please, which protein secondary structure is more stable as a single stand-alone element, alpha or b-sheet?
A question, if the formation of a-helices and b-sheets depend exclusively on the H-bonds of the polypeptide backbone, and not on the side chains (which are variable), what does determine if an a-helix or b-sheet will take place? Because the N-H and C=O of the backbone will always be the same!

Is the beta sheet consist of more than one peptide/polypeptide chain and beta turns connected them to result in a one polypeptide chain? or it is one polypeptide chain and the side that turns it called beta turns?
Jumana S both can be the case
thank you for the lecture, make me understand easily.. by the way, can u explain the omega loop structure too?
Beta paleted structure is composed by alpha helix or directly?
والله كفو, احسن من د نبيل تبعنا
i've my phD proficiency exam tomorrow and i'was prepared with your amazing videos. wish me luck:)
semiramis yilmaz good luck! let me know how it turns out!
+semiramis yilmaz how did it go ?
The world will never know"

Thank you so much Sir ❤️
sir you are a great keep it up
seriously sir....ur lectures are awesome
u r also osm

Do you have a video on super secondary, and phi, psi, omega bondage?
Super secondary are motifs..go for Garet
Good lecture bro, i have a question. can you show right handed and left handed cross over connection in parallel beta sheet. i have a doubt in understanding why the images in books look opposite ( i mean the right handed one looks left hand to me, I think i am interpreting those images wrongly)
GENIUS!!!!!!!!!!!!!!
sir your lectures are amazing.
I also request you to make a video on Ramachandran plot.
Thank you sir
thanks...😍
