How amino acids (including ones in zwitterion form) form peptide bonds (peptide linkages) through a condensation reaction (dehydration synthesis).
Biology on Khan Academy: Life is beautiful! From atoms to cells, from genes to proteins, from populations to ecosystems, biology is the study of the fascinating and intricate systems that make life possible. Dive in to learn more about the many branches of biology and why they are exciting and important. Covers topics seen in a high school or first-year college biology course.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

Watching this while crying thank you biochem😍
And am crying after watching this
Ain't that just a mood😔🤙🏼
I am 31 and still learning and crying.
samedt :
why crying??
We should all contribute so MCAT section of Khan Academy doesn't get retired!! This is a heritage!Please don't take it away!
🇦🇱🇦🇱🇦🇱
Thank you! I have watched so many of your videos and they are all so helpful. Wouldn't have passed Chemistry without you.
just don't involve in the meth business
good peptalk
Thanks. Reading neurobiology, just realized how much chemistry I need to refresh lol.
You have no idea how long i've been stuck googling "what is a peptide". Thank you!
Same
You viewing the comments, study!
Shut up
mehh on break
Thenk
nah
sorry
Khan sir ko sab ata hai ....pehle bas patna mein padhate the hindi mein ab english mein bhi🤗🤗
this content is valueable so for this we should learn english
Thanks, I was struggling with human anatomy and physiology, but now I've watched this, I understand it clearly.
Test in a few hours🫠
Thanks a bunch)))
Can you please explain what Is a partial double Bond of peptide linkage?
Thank you
Thanks for the presentation. Very helpful. However, my understanding is the ribosome flips every other amino acid so that R groups alternate on the "north" and "south" sides of the polypeptide. This alternating of R groups increases the functionality and stability of the polypeptide. If I am in error over this key feature, my apologies, but the biochemistry seems to support this key difference than what you have shown here.
OMGGG this is the exact video I needed. Thank you so much
I have watched so many videos but your video cleared my dout thanks
Your videos seem to be very helpful but I can't get myself to wait for what seems like forever for someone to finish writing what the speaker is saying! Maybe make the text appear as you are saying it? Just a bit of hopefully constructive feedback. Otherwise, vids are great!
Pearl Faraj You can get the text by clicking on the three dots in the upper rigt corner. The title 'Captions' provides the text
The number of bonds when 5 amino acids formed a primary structure?
Can u pls answer this? If 2 proteins on hydrolysis gives identical amino acids yet why they are different?
Very well done mechanistic organic explanation.
Why is the Nitrogen (amid group) nucleophil? Isn't it electrophile and how come it's not carboxy acid who does the nucleophilic attack?
Also the amino acids radical side chain (on the alpha carbon) - doesn't they sit countersite of eachother in order to minimize the steric hindrance?
Also - this is stabile (not turning around its own axis at the peptid bound due to the resonsance of the double bound oxygen at the peptid bound can swap to the peptid bound and create a pi bound between carbon and nitrogen?)
I hope someone can either confirm or push me in the right direction - thank you.
Thanks you've really simplified it
Woww, thanks bruh, it’s being to me so easy now

Your narrative is brilliant; akin to a book that was brilliant in its thematic exploration. "The Art of Meaningful Relationships in the 21st Century" by Leo Flint
Sir this is the formation of peptide bond but how we can break the peptide bond? 🤔
yeeeaaahhh...... i know some of these words...
Thank you for this video.
You should do a video about analytical mechanics and the Lagrangian.
with zwitterions being in a physiologal ph. What ph make them turn into an amino acid?
What about Proline ?
It's the same with Proline...the only difference is that it can adopt cis/trans more readily due to the difference in steric forces compared to the other AAs.
Is it for olevels or a levels??
It's freaking 2am in here and here I am, crazily stressed and crying 😀 because of my assignment
Why don't the Ns have three attached Hs and a positive formal charge? If they did, that lone pair wouldn't be on the N and wouldn't be able to form a bond with the carboxyl group.
Heeeeelpp!!! how to form peptide with proline?
AMAZING VIDEO! Very clear mechanism!
the mechanism does not make sense, I had to search up the arrow mechanism to actually udnerstand it.
Excellent 👏🏼
The linkage refers to the entire functional group, while the bond is the N-CO bond.
whats the average length of magnesium? Help would be much appreciated. Iam really struggling to find an answer
Did you find the answer?
Thanks. It really helped me understand this better. :)
All this happens in salt or fresh H20? Can you prove this in a lab instead of diagrams and explanations?
I like that
I thought nitrogen can only form 3 bonds? In zwitterion form why does nitrogen have 3 hydrogen bonds and 1 carbon?
Yes i want to ask the same question !!
I was just looking at dihedral angles and end up here. How?
That doesn't make sense (around 1:15) , you say a PEPTIDE = chain of amino acids, and then you go on to put two amino acids together and you call it a DIPEPTIDE. so if an amino acid links with another is it a peptide or a dipeptide?
its only two amino acids bonded then it is a peptide,, but if there is two peptides together then its a dipeptide, and if theres more than two peptides then its called a polypeptide

Sebastian Sandoval And the first wrong one too :) Lol comment**
I just realised how much I skipped over(-_-;)
Hit me up on Zwitter
if you enjoy this stuff, trust me you need to get out more
