Just one note: An amide link/bond is the bond between the hydroxyl group in the carboxyl group of one molecule and the amino group in another molecule. A peptide link is a specific type of amide bond that occurs between amino acids links, which holds together polypeptides.
I remember watching your video 2-3 years back for my O Level Exams and here I'm again watching you one day before my 12th Chemistry Exam, Thank you so much for all the work that you've put in, It's so so so helpful that I cannot even describe. Tysfm ❤
I never agreed with the definition of polymer applied to DNA. Polymer by definition is a chain of identical molecules (monomers). DNA is not it. The backbone is, no argument but not the actual DNA molecule. Think about it, the basepairs are a code and never really repeat. Thats the whole point.
polymers isnt a chain of identical monomers, they could be different. Take polyesters for example, they are comprised of a chain of two different monomers, a dicarboxylic acid monomer and a diol monomer.

Another great vid! I love your style. Not many science channels out there like yours.
OMG i cant stress how absolutly brilliantly you explain.
Reccommend to everyone.
Just wish you had something for English GCSE. :)
Thank you Ekaterina!!! 🤩

you have no idea how much this helped, tysm for this video!
you guys are the best gcse vídeos out there! please never stop!
I’m In year 8 and we’re doing this! so even tho it’s a video for GCSE it’s helpful for me so thanks!
I guess you're with us now though
Damn what kinda school u in how the hell they making u do this in 8 here i am struggling in 10th
THANK YOU SO MUCH FOR SAVING MY LIFE AAAAAAAAARRR
we kinda got the same name
thanks this really helped :)
Very well explained, I found this video while trying to find another video on forming amino acids with an impact test - is that actually possible?
Just one thing to note that then NH2 end of the amino acid is an amine not amino
amine group and amino group are the same
Can any of these natural polymers be used post surgery to reduce adhesions?

bruh i agree there's probably some explanation for it though?

i could be wrong as im still taking my gcses but this is my interpretation of it
this was sooo useful thank you! im pretty sure youre the king of saving us private candidates
Thanks Liam, really glad we could help 😊
