Ramachandran Principle: Protein Atomic Clashes vs. Phi & Psi

Animated atomic models illustrating Phi and Psi dihedral (torsion) angles in proteins, and how atomic clashes make certain angles impossible, favoring the secondary structures of alpha helices, beta sheets, and turns. Clashes are shown forming in real time as phi or psi rotate. Related resources:

The best Ramachandran plot video out there! Many thanks!

Wow. Just wow. I’ve been struggling to imagine these angles with my head nor by looking at the textbook. This solved the problem!!!!!!! Thank you so much!!!!

I just want to say here because I don't think this is mentioned enough but this video is perfect for visual learners and especially students with ADHD. This is definitely the best ramachandran plot video and visualization I have seen! P.S. I am a BME PhD student with ADHD who came in with a non-biology engineering background currently thrown into graduate biochemistry so if this 1 video can bring a part of an entire biochem course chapter together then you deserve to know how awesome this is!

The first time I actually understood Ramachandran plot and the phi and psi angle!!! (I first came across it during first year uni and now I have graduated) It's so hard to understand without animation. Thanks a lot!!!!!!!!

Thank you so much for making this, i was beginning to think id never understand phi and psi angles, after your video i was left wondering why i thought i couldnt

Noting but gratitude to you, SIr. And the best part is you enable teachers to present this material, and they can choose not to mention your name. This is truly what open knowledge is, and it cannot come from small minds. I'll strive to achieve this kind of mindset. Thanks a ton.
