Primary, secondary, tertiary and quaternary protein structure. Thinking about how the different factors impacting a protein's structure. Beta pleated sheets. Alpha helices.
Biology on Khan Academy: Life is beautiful! From atoms to cells, from genes to proteins, from populations to ecosystems, biology is the study of the fascinating and intricate systems that make life possible. Dive in to learn more about the many branches of biology and why they are exciting and important. Covers topics seen in a high school or first-year college biology course.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

Why have I not heard of this channel before? Time to bingewatch!
Actually understand the beta strands and sheets now. my book explained so horribly. Thank you!!
I love Khanacademy. Takes really complex things and explain them in such an easy to understand way. Great video!
God bless this guys soul
Thank u veryyyyy muh sir!! I've never been this much grateful towards your videos before!! This topic was such a headache, i couldn't understand anything despite trying really hard. Now you've made it super easy. Thank u v much
Anyone come from khanacademymedicine and the four levels of protein structure and not understand a single thing? Now I do thanks to khan!
omg
yes
it was such a great job that any thanks can't match it
Thank you very very much.Your explanation and the shapes and colors you decided to teach were the best to make me understand different structures of protein:))I really appreciate your help!
This was this was actually this was actually quite a good a good this was actually quite a good explanation explanation.
😂😂
Thank you!!!!
Really Thank you you are fantastic
Greetings from Middle east
Thank you so much ! Was so helpful :-)
There it is...
At last.... And here we goooo...
Thank you so much! My book is a disaster talking about all the fancy words without any clear explanation...OMG
Thanks!!!
more understanding than Campbell book
thank you for this great video!
You are my best always great
what he used to draw and write?
Mistake:
In case of anti parallel, 2 polypeptides have opposite ends facing each other i.e. N facing C and vice versa
thank youuuuuuu
Is there any purpose to considering the process to have 4 stages, except that it is convenient from a semantic perspective? It would seem more fundamental to consider just the variables of the structure - attraction, repulsion and bonds, and then the flexibility of each unit and origin/size. As it would seem not fundamental to stop at 4 levels, but potentially go on forever assuming it was big enough, with new structures forming each time previously created structures interact?
I guess I'm saying, it seems more like a continuous process that we've decided has 4 parts? Or is there only ever 4 distinct stages, each with fundamental differences necessitating the labels?
I agree. I’m only just learning the basics of chemistry. And I was wondering the same thing. It seems to be unnecessary (and also seems to happen a lot in chemistry 😅). Understanding the ways these amino acids and polypeptide chains interact with each other is great and all. But must we try to label those interactions? Especially cus like you said, there could potentially be so many ways proteins are formed and so what’s the actual point? Unless there’s only a few main ways that it happens. Then, I guess 🙄
At the very least, I don’t see the difference between the tertiary and quaternary structure. All of shows is that it continues to take different shapes and build on.

oh no, i got the banana stuck; all the way.
I'm going back a few videos, finding it hard to follow.
Great video. Explained it so much better than my useless teacher.
i lost in your voice 😍😍

didnt draw the alpha upside down. literally unintelligible
