Proteins play countless roles throughout the biological world, from catalyzing chemical reactions to building the structures of all living things.
Despite this wide range of functions all proteins are made out of the same twenty amino acids, but combined in different ways. The way these twenty amino acids are arranged dictates the folding of the protein into its unique final shape. Since protein function is based on the ability to recognize and bind to specific molecules, having the correct shape is critical for proteins to do their jobs correctly.

Animation by Maria Voigt, narration by Monica Sekharan
No more distracting music. A new version of this video is available at czcams.com/video/wvTv8TqWC48/video.html
Thank you for this great video. Please produce more.
Do You have something on sinthesys of antibiotics?
I need this. Thanks!!
This video brought stress to my biology class.
Exactly
"Wait'll ya' get a look at [DNA] ...
'Whoop, whoooop!' "
Same, I'm currently suffering because I feel like I don't understand anything that was discussed in this video
good info but the background music is just plain distracting
Am I playing Runescape?
Nazeef Vasaya ugh it's like kill me now
rly? I find it (and the whole video really) strangely calming 😆
idk
My undergraduates is in biochemistry. That was great- we didn't have such a nice short synopsis of proteins when I was in school. You had to hunt and peck to get your way through it. I swear it was like they were keeping it a secret. Thanks for sharing.
Yes the evolutionist do not want the Beauty of this Intricate Design to spread doubt that all these 100 of thousands of combinations Replicate just by chance
Talks too fast and the background music is too loud.

then slow the video down
Please get rid of that background music and play something a little less circus-y
Cripe, the background music is distracting, and the volume of it overrides the overly-fast narration. Good animation, but please remake this.
wtf is this music
MorningStar "waa, waa, wee, wee, waa-wee-waa, wee, wee" aaaaand repeat!
I love proteins !!! Such a marvelous machines I have ever seen !!! The blueprint of their construction (DNA) is just mind boggling !!!
As a mathematical physicist, I become more interested in biology, specially the recent shocking findings that plants use complex quantum physics technique to boost the efficiency of photosynthesis.
A very illustrative video of what happens on a molecular scale
EXCELLENT VIDEO on protein structure !! 😁👍🏻👍🏻 .. gonna be helpful for my students to understand better !!
wow!
so enlightened by this video, I was kind of finding it hard to understand about the structures before watching it :-D
This video was perfect. Thank you very much!
I like the animations that you used! Great video
So what are proteins again?
Made of amino acids which can be broken down to carboxylic acids
Background music is very distracting
be slow and calm while understanding others so that they can be benifited
Background music.... Best.... I loved it.....
She does talk VERY fast for all that info! Fortunately, you can slow the audio speed if you wish. Use settings to go as slow as 1/4 speed (.25).
The music is so distracting
This is perfect! Thank you!
The commentator needs to speak more clearly and slowly. Too much information for 3-4 minutes, would have been better to split it into several videos.
can i use this video on my project?
so proteins are structures made from amino acids that facilitate the function of each organ and the body as a whole. is that right?
Everyone's annoyed by the background music, I'm hypnotized by it! What's its name? XD
really very nice, thank you for knowledge sharing :)
I find it a bit difficult to understand you because you're speaking swiftly but great video anyway! Keep it up!!
Thanks a lot for sharing such an amazing video! Helps me a lot as a university teacher! :)
Larissa Consoli, this video has been updated and the new version is available here:czcams.com/video/wvTv8TqWC48/video.html&lc=z23vcljgexnxtv0lhacdp430yiv1sjrjtoo5ggc30pdw03c010cHope this will be even more helpful.
The information is really helpful but she talks sooo fast I have to pause every 3 seconds to write stuff down and the distracting background music makes it worse!!
Excellent visual presentation
Jesus, change the background music!!!!
what a beautiful and useful video~
Music in the background is extremely annoying but the video was extremely helpful. Thanks!
What is this song can anyone help
This was helpful but the narration was a little too fast. I'm trying to process and understand and need to hear it a little slower :)
Than just slow down the video
Looks great!
thank you for knowledge sharing
Very helpful video thank you
The explanation is excellent but the background music is a distraction for me🙋
I WAS SO CONFUSED ABOUT THE R GROUP THINGY IM SO GLAD I CLOCKED ON THIS VIDEOOO
It is really very helpful..
用意できた！
🤔
The audio volume is very low
This is terrific, but the music is really distracting.
Oh no how will you live?
Oh, hi charlie
This video would fit my learning style. So simple. 👁️👁️👅👁️👁️
lovin the channel!!
Such a shame that sound quality and background noise (music).
I want to use this video for my open educational resource course on Protein structures & functions under CC-BY-NC licence. Please allow us to use it. Thanks.
You are welcome to use the video. Please credit the RCSB Protein Data Bank. Good luck with the course.
For this sort of didactic work, which is rather complex and difficult, the author would do best in chosing a reader who can speak slowly and pronounce his words clearly. This is nearly brain wrecking to understnd at first visionning, and when you get to the end the first time, you have by necessity had to go over the video at least five times, just to understand ONCE. This speed talking is just what is absolutely unbearable on videos - plus the music indeed is too loud and does not add anything to the quality of the didactic content : on the opposite, it takes away audibility and comprehension. Authors, please, heed, when you are making these otherwise interesting videos. Thank you.
Thanks for the effort and good continuation in video making,
MMEJones
plz fr nxt vedioes audio shuld be bit high
Dat beat goin hard my boi
this is great thanks
the music makes it more interesting. plus if the musics too distracting, that's a sign you're not really paying attention to the content
very nice
Super explanation
Great info
RCSCProteinDataBank: Would you be willing to re-do this video and explain in layman's terms (with out that music)?
The new version of this video will be available in about 2 weeks. Stay tuned!
Thanks for useful informations
Not all amino acids have a sulphur group, still informative demonstration
Turn up the sound 🔉 please ?
1st version is much better than the 2nd one
los videos en ingles dan progeria
अति उत्तम विख्यान धन्यवाद
This is a great video, but it goes a bit too quickly for many students to follow.
***** Sorry i don't understand the last sentence.
Good
CTRL, ALT, DEL
this music is so calming
Funny how Carboxyl and Amino Groups make the polymerized Chains that form a Protein, while Deoxyribose Sugar and Phosphate Group make the Backbones that form DNA. All as, respectively, the Amino Acid's Side Chain gives a Protein it's Properties while the Nucleoside's Nitrogeneous Base (it's 'side chain') records it's Information.
... that will later be used (via Codons) to select for the Protein's Properties.
Is it not then possible to make the conjecture that Life, as distinct from mere 'clockwork' Physics, is a self-sustaining Chemical System that inserts into the chain of emergent properties in the Universe a means for using Information to Select for the Variability and Emergence of such Properties.
Beautiful
one thing i cant understand is that there are only 20 amino acids and our body has millions of proteins ...then how can only 20 amino acids make sucha large number of proteins
The amino acids can link together to form chains of at least 100 amino acids long, and it's possible to form longer chains. This, combined with the shape & folding of the protein, and the order of the amino acids in the protein, provides a long list of combinations.
To make things easier to explain, take a dipeptide. As the name suggests, it has 2 amino acids in it. 20^2 = 400. So there can be 400 dipeptides using the amino acids that are necessary in the human body. Do the same thing with 100 amino acids in a chain, and you get 20^100 = 1.267651e+130 = 1.267651 * 10^130. 10^130 is 1 followed by *130* zeros!
A freak in a masterpiece.
Hey... What's up? Chem class from edcc.
THANK YOU
best understud
What miraculous God Actions and design
bello il video
nice music
Thank u
Is anyone here from the "Biology 1" digital textbook of The Swedish National Encyclopedia?
Är någon här från Nationalencyklopedins digitala lärobok "Biologi 1"?
Wow this cool
how to detect in body? how and where medic found the evidence proof truth from invention , development to doctors verify coverages for certify truth 100 right for astudents goes on edu and take operation for patients ( any details labs reports proof effective ? )
It would be better if you talked slower so it can be absorbed that is unless you are trying to impress people. The point is to learn here.
Buenísimo
merci
voice quality is so bad
I found the music so distracting, please re-edit this and re-upload. A lot of other people seem to have the same complaint, and I cannot understand as to why you haven't done it already.
true!
omg you speak SO fast :O

When you think about protein, athletes and bodybuilders may come to mind, but there’s much more to it than increasing muscle mass. Protein plays an essential role in keeping your body healthy. So, how much protein do you need? And is there such a thing as too much?
good structure
The voice speaks too quickly and quietly for this to be at all educational. I'm getting maybe 10% of the words?
ah yes i agree mr nice video choice.
3d structure of cell
no le entiendo pinshi maestra enana por que nos deja URL 'S en inglés :'v
GET RID OF THAT MUSIC!!!!!!!!!!!!!
TALK SLOWER AND MORE CLEARLY!!!!!!!!!!!!!!!!!
Beautiful animation. Wide ranging and concise presentation. Thanks for the creation.
I have protein videos as well and frequent RSCB.
Please check out my videos; I'm DIY studio in a garage, but putting my all into and learning a lot. I'll put link in next comment.
Thanks!
My lecturer brought me here
