Its criminal that my professor expected me to know this without this type of explanation

There's no way I'd have grasped the concept of these torsion angles if it weren't for this video. I owe you my life, no jokes.

If you didn't understand the concept by watching this video, watch it again more carefully
This is the best video out here on yt explaining this matter

I truly did not understand phi/psi angles and Ramachandran plots until watching this video. It was really helpful, thanks!

Thanks to your video and the tutorial link.. without this it was impossible to understand the concept. As no text book describes with this much clarity.

This is the best video on dihedral angles out there!

VERY clear video, thanks! You'd think "basic" stuff like phi and psi would be difficult to forget but apparently not.
My mnemonic; "NCC phi psi"; phi N-CC, psi NC-C. Middle C being the alpha carbon, of course - kinda intuitive and easy to remember since N -> C and "phi psi" is in alphabetical order (h before s; phi before psi)

Great job, this video allowed me to understand what I have been not understood for 3 years now.
