    Anyone come from khanacademymedicine and the four levels of protein structure and not understand a single thing? Now I do thanks to khan!

    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!

    Mistake:
    In case of anti parallel, 2 polypeptides have opposite ends facing each other i.e. N facing C and vice versa

    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?

    • @AandM8
      @AandM8 Před 2 lety

      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 🙄

    • @AandM8
      @AandM8 Před 2 lety

      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.
