Protein Structure and Folding
After a polypeptide is produced in protein synthesis, it's not necessarily a functional protein yet! Explore protein folding that occurs within levels of protein structure with the Amoeba Sisters! Primary, secondary, tertiary, and quaternary protein structure levels are briefly discussed. Video also mentions chaperonins (chaperone proteins) and how proteins can be denatured.

I was reviewing for my biology exam and wow am I glad I ran into this video. It follows the same basic information of my notes, but the illustrations make it much more comprehensible and memorable. Thank you!
Everything about this video is super helpful! The animations, the explanations, and even the voice, as weird as that sounds, but the narrator sounds so enthusiastic that it helps to pay attention and actually retain the information, rather than a monotone robotic bio teacher. THANK YOU!!!
I have an honors human anatomy/physiology exam tomorrow, this is helping a lot!! I love how you mention the way that shape effects function and have so many visuals, THANK YOU
Thank goodness for your channel. Y'all's video help me so much in biology class.

Pre-med Biology Student here and these videos are so insightful. The pictures are a brilliant touch I find myself memorizing the info and retaining it better.
I literally love this channel they make me giggle while learning biochem
You guys are doing an excellent job at explaining science based concepts ! Thank you your hard work!
I swear you have been saving my life for so many years and each time you make me love biology more and more
Thank you so much for your efforts, Amoeba sisters! Never knew Amoebas could be this good at teaching!
Amazing! This topic has been very abstract and intimidating but after watching this, not only do I understand better , I actually found it rather interesting and fun! Where have you guys been all my life!!!! Great job !
Amoeba sisters, thank you so so so much for all your videos, the animations coupled with clear narration and ingenious way of explaining things, make learning biology FUN! I really cannot thank you guys enough. Continue your great work !
Just in time! My lecturer is currently covering Protein Structures and I was soooo lost :')
A BIG BIG THANK YOU AMOEBA SISTERS FOR MAKING SUCH CONCEPTS WAY MORE EASIER TO UNDERSTAND😭😭😭 ~ THANK YOU SO MUCH!!!!♥️♥️
I was searching for something more complex, but your video, I must confess, has made my day with those funny animations. Big support to continue your work like this 😄
You are a life saver, I have spent the past few hours using your videos to study for a physiology exam. Thanks amoeba sisters
Soooooo underrated channel! What you are presenting is absolute awesomeness!
Only word I can utter after watching this video is : WOW !!!!!!! How can someone explain so excellently.
From freshman biology in highschool to my senior biology classes as a biology student in college, the amoeba sisters have helped the whole way through
So lucky to have a site to run to when my readings sometimes don't add up! You girls are amazing.
Just stumbled upon your channel, but I really love the way you distill the concepts and make the material engaging with the images!
Thank you! I remember getting confused when I learned this in HS and the textbook I have now in college didn't explain it well at all. This made so much sense!
Doing this in college, thank you so much! It's really hard to find entertaining visual learning supplements, but you provide so well! Thank you
AWESOME WORK! This is really helpful! I'm a master student struggling with this adult life and having a fun way of learning is always appreciated, thank you!!!
Your videos are a blessing! Both the narration and the drawings are amazing!!!!
I have been using the Folding @ Home program on the PS3 long ago (it was fun while it lasted, though...), and that got me intrigued about protein folding. Now this video made more sense and gave me enough resolve to want to contribute more to protein folding. Thank you, Amoeba Sisters! You just earned yourselves another subscriber. :D
Hah, I remember these videos from Bio 1. I’m so glad that y’all are still making ‘em!
Great timing. My exam is tomorrow and this is included. Thank you for simply explaining it!
this was so cute and y'all should have so many more followers!!! I needed something to still feel productive yet simplified ty!
I love the videos! Thank you for sharing your knowledge and making the content relatable with the images and comics. Keep up the great work.
Wow! Great video helped me pass all my midterms! Totally recommend! 💕 way better than crash course!
I'm watching this for my college biology class. This makes so much more sense . Thanks for the great video. :)
Wow! Amazing videos on your channel. I am a Turkish student attending to a German school here in Turkey, yet I still learn by watching your videos in another language. Very helpful and nicely animated. Thank you! Keep up your great work!
You both are so amazing, your videos explain everything so perfectly. I appreciate your efforts!
This animation helps with good understanding and keeping the information and lesson in the memory. I wish our schools would reconsider the way they deliver lessons.
You have no idea how helpful your videos are for me understanding the concepts of my college biology class. Thank you so much. It being online makes it so much harder and seeing these things being animated and told about in these ways really helps it stick to my brain and allow me to understand it more. So thanks! You girls are a lifesaver!
Amazing simplified explanation as always. It helps a lot.
Genuinely amazing breakdown, managed to explain a totally indecipherable 1 hour lecture (even with the assistance of other students' notes) in under 8 minutes
This is a really awesome video! You guys have an great way of explaining things plus awesome animation!
Incredible amount of information from freshman to grad school refresh! Dr.Don
This channel is amazing! I request you guys to upload more videos and be my saviour of biology!♡
Wow..you two really bring the subject of biology to LIFE!
I admire your video the simple explanation makes me love biology and I really enjoy studying it
Got everything I needed to know in 3 mins! JUST PERFECT!
Your videos always save me from failing. Thank you!!
You don't know how much i love biology now. its all bcuz of u guysss. Thank you.
Omg you're the best science channel I've ever seen .. not only making learning interesting and easy but also you got cute little drawings here and there .. I am really glad that this is a think .. much love ❤❤ .. keep up the amazing work 🤩
great presentation and explanation. wish classes were more like this
Thankyou so much ...for all videos ...love the way you explain difficult concepts ..so easily...gr8 efforts
I love you, this video explained it 20x better than the textbook, Im not gonna fail the test now
This is fantastic!! Thanks so much for creating these
Thank you for explaining it so clearly and ensuring it is easy to understand!!
The level of learning i get from this videos😍
Amoeba Sisters I love you guys so much, you guys are my life savers
You are the best science channel... Iam a medical student and this channel helps me in my first year... thank you
Thanks a lot, l was so confused about the different structures of protein from my lectures, but when l watched your videos was so easy and clear to understand, you did help me with my study
thank you for being the goats of biology content, I only wish some of these videos would go a little more in depth into the topics but definitely always a good help
Someone likes your videos so much, they turned their screen upside down to like it again
I read a bunch of articles and journal and understands almost nothing about it. And I understand a lot of things just by watching 7 minute 45 seconds video. This video helping me a lot with my upcoming research
I love your videos because they clarify my concepts. (And I think you explained better than my teachers haha)
Great video very clear and all the important points explained super well!
i didnt really like science but ever since i found you girls on youtube i love Science and its the best at explaining thing to me without the confusion and the pictures are funny i love it thanks Amoeba Sisters
Two ideas for videos: 1) intro to basics of physics and chemistry for high schoolers who have gaps in their backgrounds (atoms, bonds, molecules, electrons) 2) study skills for biology class Thanks for everything!!!
Yes! This is just what I needed for my biology test tomorrow!! Thank you so much!

Love this video! Excellent explanation. 👍🏻
Good work on this video, thanks for the help!
I came to this video to see if I could I understand wtf those squiggly shapes are on chemical compounds on Wikipedia. I think I learned some new things, so thanks for this easily understandable video for an outsider to the chemical domain who has very basic knowledge of chemistry.
