This channel is among KZfaq's best sources of science education. I found these lectures extremely helpful as supplementary lessons while I worked toward an M.S. in biotechnology in 2016 and 2017. I was able to graduate and have moved on to PhD studies in biopsychology, and since I've watched hours upon hours of their videos, I must thank Andrey (the lecturer) and Alex (the developer) for creating stellar content that helped me succeed. Cheers!

Great work. You've educated thousands upon thousands of people.

miss those days that this channel was incredibly active. hope that someday if he gets more time it will be like that again:)

Very helpful videos! You help me studying for medical school, and I hope you will continue doing an amazing work that you did! Have not seen any better educators on KZfaq than you, explanations are so clear and simple. Sending huge respect from Estonia) You truly deserve millions of subscribers

The method of putting all the information there and not snapping back and forth makes it easy to keep track. I'm just here to let you know I love your work. Please continue!

Sir I couldn't find advertisement in any of your videos! And the most amazing thing is that you made a 40 min thing possible in just 8 mins👍. thanks a lot 😇

Your lectures are the best.. I actually have saved all your lectures and going to prepare for my finals from them. Thankyou so much for your videos they have made Biochemistry a lot easier than before..

Always grateful for your videos Andrey! They've help me a lot, thanks for sharing your knowledge

I cannot express how I am grateful towards you. I could say that I know what is biochemistry because of you. I believe that god will bless you since you contributed to ... well i believe to most of the medical students' biochemistry knowledge. Thank you so much!!!!!!!! God bless you!

Thank you so much for taking the time to make this!!! I'm a first-year medical student with debt (only to get bigger...), but once I have extra money I'll try to remember and pay it forward. Biochemistry is still not my favorite, but you make it a lot more digestible :)

You're an incredible teacher! Please keep doing what you're doing :)

The way this guy uses intonation and voice volume/pitch to explain is pure talent. I wish physics and chemistry subjects were explained by this guy too.

Hello Mr. AK Lecture. I am really in debt to your videos in Physics. Really, thank you very much for uploading such videos with great content. Your videos helped me passed my comprehensive exam. Goodluck for your future uploads.

Hey , it's really incredible to see the amount of time and effort you are directing in these videos . There r such a boon.!!! Keep going...Nd make your playlist for biochemistry complete. Bash on regardless !

Yasss on My Bday !!! Wonderful notification😙😙😙 THANK U !!!!

@aklectures I'm not sure if I'm able to find it but do you have a video series on symmetry? There aren't very many good resources in this area and I feel like you're one of the best KZfaq channels at explaining completely and concisely the important aspects of each topic. Keep doing great work! Thanks!

I'm so thankful, you helped me a lot .. you always make it simple to understand.

Not enough words available to appreciate your efforts, Thanks.

A man with knowledge of all sciences .........you are really great...

Thanks a lot for your videos and for the effort you put on them. I studied here for my biochem exam and it went great! Thanks again:)

Wow! I'm impressed by your work... Thank you so much for it!!!

Thank you always for your incredibly helpful videos!!

I appreciate your hard work I study from your videos , you are the best on youtube

Thank you for all of your videos that you have made for us! Currently, I'm learning about the science behind GMOs, but I'm still kind of confused about it. Could you please make a lecture on this topic? Thank you

These lectures flow so damn good lol. Can you please make a series of how to study various science subjects? I feel like individuals struggle in my classes because they are not sure how to study science or test their knowledge so they can improve. Anyways, thanks for the videos they have really helped me out.

Please keep making videos.. u really make a big difference in this world. Among all the tutors in youtube I find u the best... pleasee....... keep making videos..

he's come again !!! wonderfulll !!!

good job ....always have ease in life..your explanation eases the hard units. thank you

I am from india. You are great man. Doing so well good. Your notes is very good. I have studied many channal in you tube but your channel is best . Thankyou so much sir for doing great work. In future i want to meet you guruji(sir).

Thanks a lot for occupying your time with this incredible work! Watching your videos throughout my prep for medical school, here in Italy, was really helpful (I've managed to pass!) Once again, thank you so much! :) p.s I'll keep on watching them!

Thank you very much for your hard work!

I appreciate your efforts to make such videos and give a clear understanding of the underlying concepts. But I wish if you could make some videos on molecular markers and molecular breeding concepts (genomics & mapping), which will be highly helpful. Thanks.

thank you for this great work. at least I can get from the books and video too.

Just wanted to say thanks for all your amazing videos, I ended up getting a B on my final exam because of your videos...class average was a 51%. Thank you!!!

This topic is well understood. You keep on helping like this, sir. Thanks a lot.

you are gifted from God to teach, to change our mind, and you make me to out from great desparity ,because you can express easily and simple diffcult concepts in understandable manner. sometimes I thought God blessed me by you to pave my road for my next life and you changed my undersanding level.I suggest you to fled videos apacely and start new course like other youtubers we need you. You are talented man.I ask you teach histopathology and basic clinica chemistry?

Just came here to say how great it feels like that you no longer need to know this

Awesome video, truly helpful ! thx ! Can u add the board on your website ?

Just came here to give a thumbs up :)

Your videos are very helpful I usually don’t comment but I have to thank you so, thank you so much.

im so grateful, helped alot. Just one tiny typo i guess at the transformation of Adenylosuccinate to Adenylate the enzyme is (Lyase) type not (Synthetase).

I think I've fallen in love with this man

you have the best sciences channel on youtube

Amazing, thank you so much!

Thank you for this treasure trove of information, I am studying number theory and mathematics but have been flirting with bio and pathology for the last year or so. Its great to be able to see the real "meat" of the field without having to dump 2000$ into a class.

His videos are awesome man......................................................... A video after long time though..

I am missing your lectures so much please try to make some time for all of us. I really want to meet you one day and want to say thank you for incredible lectures. please come back, please. Heartly request from one of your students.

Great video and explaining! just have to adjust something, to actually create IMP out of 5-phorybosyl-amine in these 10 Steps we dont only need aspartat , glycine and tetrahydrofolat we also need HCO3 and Glutamine.CO2 donates a C-atom and Glutamine donates a N-Atom. however as I said great video, keep up the good work. greetings from Germany

How did you know I was studying this 😭😭😭

Thanks a lot these lectures are helping me a lot in biochemistry exam 👍👊

Please update with more molecular biology videos I really appreciate that !

Your all video lectures are amazing n very useful for me thaqqq for all lectures..............

Sir I can find only the video of de novo synthesis of pyrimidines on your channel and website...I need the salvage pathway too... Please help

Very useful! Thank you!

I love your videos they are all great. sir I have a request if you can make a video on Ramachandran plot, that will be very helpful..thanks

Plz come back ak lecture .I am your biggest fan . You are genius

Your teachings are great..! I really wish that you would put some basic chemistry up here 😁 Like counting and so on

So helpful... love from Pakistan

Isn't Adenylosuccinate lyase used in the 2nd step in generating AMP? Or are they the same enzyme? Because the 2nd step isn't using an energy providing substrate like synthetases use.

Thank you so much for your lectures.. could you please give a brief lecture on DNA bending and supercoiling..plzz

Plz explain purine and pyrimidine degradation...love from kashmir

Great work!!!! Thank you :)

IS THERE ANYTHING YOU DON'T KNOW ??? Kidding :) Keep it up

You are amazing!!! plz explain difficult parts of pharmaceutical chemistry :)

can I get a video on purine and pyrimidine degradation. pls

He is awesome! please a video in porphyrin

I would die for AK lectures

Thank you so much for this lecture

Helping me through med school one video at a time. =D

I want to give you an advice as an experienced teacher I am. If you want to be more successful in your teaching job try to write while you talk, because this is the best method to teach people and alsa it recognises teachers from REAL TEACHERS.

Wonderful explanation of the hardest subject.

It is really helpful!

Thank you so much

hi can you do a whole unit on evoloution? like first cells, protocells?

why did u stopped?​

why do we utilize GTP for AMP synthesis and ATP for GMP synthesis?

Great explanation

There is a mistake: the second reaction of AMP synthesis is made by ADSL and not by ADSS.

Visited your website and realized you live near me :o

Is there any video explaining those 10 steps?

you are awesome !! please please .upload a lecture in taxonomy

do we use two glutamines and two THFs? Thank you

Are you from Brooklyn by any chance?

Can you make a video on laws of gasses

Well done man 👍 helpful videos

He is so cute.

God will bless you, Boss

Thank you so much ") also, can you explain another subject? About plant and animal Biotechnology I need it for my exam 😭

Outstanding 😍

Please do a video on porphyrin metabolism

You are a biochemistery angle🌻❤

i cant find the playlist :(

why did you stop!!!!

Hello Sir my Q is regarding adenylosuccinate synthetase enzyme, it shows that it catalyzes both steps, shudnt it be AMP synthetase for the last step instead🤔🤔?

very very thanks sir, make more videos for us .

Great job sir

Sir can make video on different types of bioreactor

Ur lecturez r great but I didn't find cholesterol synthesis and nucleotide metabolism ...can u plz send me these lctures

Please make videos on bioprocess engineering...please

Thank you sir.
