What is a Protein? (from PDB-101)

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 one 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.

Very informative for the average lay person. Now I just need to watch it 10 times over to absorb it all.

[Coachnickhawley]

It's totally mind blowing to think about all the complexity involved in just living day to day. It makes me appreciate life more when I watch things like this. Thank you for putting the effort into this incredibly thoughtful video.

This material can be considered an oracle. Animating the processes and the logic of how molecules rearrange is illuminating. The illustrations are of top quality.

[tylerpedigo]

This video is incredible. Great work on the simulations.

[TrishTruitt]

This is excellent! I learned more in this short video that in a 50 minute biology class. Great animations, narration and sound effects.

[MultiSciGeek]

Perfect explanation and top grade simulations!

[artofchickens]

This video is much better than the other "What is a Protein" video. Thanks so much!

[paulwalsh]

WHERE HAS THIS VIDEO BEEN ALL MY LIFE ? !
So much information, so well explained ! Well done, thank you !

[kristyanne]

One of the most interesting and informative videos I have seen in a long time! Really explains it in easy to understand terms.

[letbe]

This. Is. Amazing. Adding to a list of videos I will be rewatching repeatedly to absorb this material. Thanks!

[asdfasdfasdfasdf]

…one of the best videos I’ve seen on protein definition, structure, and function.

A lot of work went into making this look simple

Hats off to the team involved.

[kuhataparunks]

Thank you so much for the animations they really help clarify the bland photos of the books

[HiAdrian]

Such a concise and well made presentation, thank you!

[handsonfire]

this video was absoulutly stunning, thank you so much for all of the time and effort you put in to make it as comprehensive and concise as you did.

[sebipalma]

This is such an informative video and I love it. The animations are incredible and extremely helpful.

[nofurtherwest]

i feel like i've learned more than in my entire biology class

[OmegaUberDeathbot]

The first time I have seen a accurate representation of protein functions without losing important points. I finally understand protein folding!

[lucasfc]

WOW the production and scripting value in this was perfect! It is concise but just enough for the casual viewer, great!

[renatobalestra]

Thanks everyone that helped and support to produce this amazing video!!!

[madalchemist]

Excellent video for people taking a level biology in igcse. The animations are amazing, the sound effects visualise everything in our head and the music is really cool! The proteins look very accurate to what a stereotypical protein would look like.
