Understanding PHI and PSI Angles, Ramachandran Plots, & Newman Projections

[@mateoortiz8525]

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

[@_jeena]

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.

[@gg025]

im glad im not the only one

[@chakubanga1]

Hahahaha. NO Comments. Otherwise the list will get longer 😂😂😂😂

[@scruffymakaveli6870]

Criminally underrated video. You are awesome.

[@me-bw9cz]

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

[@gyaneshshukla1946]

The best Ramachandran plot explaination on the internet.

[@rabrojonel]

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

[@mimosveta]

I don't think those who wrote my book understood them either. like, at no point did they clarify that 6 atoms were co-planar, which to me seems kinda crucial...

[@goncalosoares8420]

been reading my ptts for more than an hour and understood more from these 10 minutes . . .

[@abhyarthanabehera4802]

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.

[@dmajumdar2059]

This is the best video on dihedral angles out there!

[@levydo8051]

This saved me from hours struggling understanding phi and psi angles

[@Clockworkbio]

Oh you KNOW it's a good day when there's a new Molecular Memory tutorial!

[@astrobiojoe7283]

This is the best video on dihedral angles!

[@adhoccerswings]

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)

[@MolecularMemory]

Thanks for sharing your mnemonic!

[@adwaitdighe4342]

cool!...h before s 🤣🤣

[@sathyamurthys9855]

THANK YOU FOR THE VIDEO MAKER AND THE PROTEOPEDIA FOR PROVING SUCH DETAILED EXPLANATION

[@jhankargarg7327]

Both the video and the link provided in description is very helpful Thank you for making my concept clear. It was so confusing earlier

[@jdmccool1]

You do such a great job at visualization that it would be awesome if you could make a video series around group theory. Symmetry is so hard to visualize and I feel you would do an awesome job!

[@gabrielqin9687]

Hi, is there any recommendation for group theory? I am a math-beginner for a biology major, but currently I need to deal with Euclidean group in molecular symmetry.

[@julianadawood3829]

first biochem exam this friday, you saved me with this!

[@Dabonthehaters123-l4b]

So true girl

[@marahsaad9047]

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

[@shafiurrahaman3396]

Incredibly helpful video on these dihedral angles, i for one really struggled to understand phi and psi from static 2D images - (for me they seemed to always be 180 in diagrams!). As soon as the image rotated in 3D space it all clicked and the clock diagrams were a nice touch as well for keeping track.

[@trixstandflipped]

Fantastic video with awesome visualizations. Thanks!

[@rajatkumarparida4542]

thanks a lot for the amazing visualization, and this is helpful to me......

[@yazzydrazzy]

What an amazing video!!! Thank you so much

[@sudippattanayek6760]

You have done an excellent presentation.

[@ogunoluwamayowa4749]

You always have a way of explaining things in an awesome way

[@shujahat_8c]

Why do we study this

[@Helpnote9987]

To figure out the specific rotation of the N-c alpha and c-c alpha bonds of amino acids residues that forms peptide bonds .

[@rachel_dare3662]

To pass the exam ofcz

[@burrito1413]

To fight diseases by understanding the proteins intrinsic properties

[@jameelabduljalil25]

To understand protein 3D structure and folding.

[@김인린]

Biochem importance. Apparently these angles help with biological functions in proteins etc

[@mathiasverbeke9817]

A great visualization, thanks!

[@raziamubarik9468]

Thank you providing a detailed video! Bless you!

[@johnman1626]

Really really osum explanation great work

[@anirbanbhowmik1416]

Thank you very much for this video! I might have never figured out what these dihedral angles phi and psi actually mean from those textbook descriptions. You know, they should really suggest something like a student should refer to a good KZbin video for a better understanding, sometimes. And, I don't think not many people understand this concept clearly (even those who've been teaching this). Thank you very much! ❤️✨

[@SherKhan0122]

Brilliant video. Thanks!

[@doctorumar1700]

excellent PLEASE KEEP THIS CONTINUE

[@franklinpulikkottil7826]

Amazing! Concise and understandable ☺️ Thanks a lot. And for the proteiopedia link

[@nickm9893]

Great animation, great explanation!

[@divyanshdixit933]

Thank you for this, I'll be forever grateful 💓

[@rehabalsaleh166]

Amazing! Thanks a lot! This definitely helped.

[@Theabok853]

Excellent video and explanation

[@tamilbiology5078]

Dr Gn Ramachandran is from my state tamilnadu , India

[@jessicalv6442]

AMAZING!!!!! Thanks!!!

[@Ash-vl5ph]

Amazing video!!

[@siddheshshewade7063]

we are saying that at particular values of phi and psi we have to look down in ramchandran plot and we will get an idea of its secondary structure but the plot u displayed is for alanine so if there is a peptide solely made up of alanine only then it can be true but if we are having variety of other amino acids in our peptide then how can we surely say that at those values corresponding will be the secondary structure. I mean the plot would have to change in that case

[@jkg6491]

From a native speaker, his name is pronounced " Rama-Chunn-Drun/Dran". Also thank you, great video yet again

[@sayanghosh123]

Great explanation, Thank Youuu

[@ishakashyap6974]

So so thankful to you...

[@mimosveta]

we people are collectively insane...

this video saved my life, thxxxx ❤❤❤❤❤

[@Hyumifu]

thank you so much!!!!!

[@ericmartz9100]

Really well done!

[@thex5772]

Thank you soooo much. I subbed

[@hansenyang4014]

Hello I am learning this outside of the textbook for research. Can I ask why the substituents on the nitrogen are 180 degrees to each other? Shouldn't the nitrogen atom also have a lone pair so the substituents have to be 120 degrees or less apart? If this is a convention in some textbooks can someone explain the logic? Thanks very much. Edit: I think I just figured it out. Since the nitrogen is in resonance with the carbonyl, it does not have a lone pair and the N atom is essentially planar with only two substituents. It looks very cursed to have two groups 180 to each other in a Newman projection.

[@jamesbean9396]

So damn clear! appreciate

[@divyarana3637]

lovely

[@syedjamal3262]

Great job

[@herrmanselcher1632]

Beautiful, thank you

[@tandelchandni1273]

yeah thank you

[@felixbaez9439]

Excelent video!

[@HydroZxZInferno]

I wonder if you would be interested in speaking at an event my university is going to hold in connection with the UK Biochemical Society for the students. I have always found your pymol videos to be extremely well explained and clear! please reply if this is something you'd be interested in. Best, Will

[@jacktietjen]

Fantastic!!!
