Thank you for watching
This video describes the constitution of peptidoglycan layer and the value of their presence onto the surface of microorganisms.
Peptidoglycan, often referred to as murein, is a polymer such as sugars and amino acids that varieties a mesh-like layer outside the plasma membrane of bacteria (but not Archaea), forming the cellphone wall. The sugar factor consists of alternating residues of β-(1,4) linked N-acetylglucosamine and N-acetylmuramic acid. Connected to the N-acetylmuramic acid is a peptide chain of three to five amino acids. The peptide chain can be move-linked to the peptide chain of one other strand forming the 3D mesh-like layer.[1] Some Archaea have a similar layer of pseudopeptidoglycan or pseudomurein, the place the sugar residues are β-(1,three) linked N-acetylglucosamine and N-acetyltalosaminuronic acid. For this reason the mobile wall of Archaea is insensitive to lysozyme.[2] Peptidoglycan serves a structural function within the bacterial phone wall, giving structural strength, as well as counteracting the osmotic stress of the cytoplasm. A original misconception is that peptidoglycan offers the cellphone its shape; nevertheless, whereas peptidoglycan helps keep the structural force of the cellphone, it is truly the MreB protein that allows mobilephone form[citation needed].[3][4] Peptidoglycan can be involved in binary fission for the period of bacterial telephone replica.

your work is awesome 👍
your explanation is so clear. thank u so much :)
bodoh puny melayu
Sir, which curriculum and grade is this for? And could you give NEET questions?
Could you further explain how the D-Ala falls off of the chain, and why does it do that?
Thank you this was helpful
Thank you !!!
i found this well explained, nice job
Glad to hear that you are getting benefit from the videos
u didnt explain biosynthesis 😫
what book is this sir? :)
Dude why don't u use lehninger for this explanation!? ..😑
lehninger or prescott
thank you 😊
thanks alot
What book is this please :)
Sir this is in which book??
Very helpful sr...tha k you so much..
You're welcome
Bonjour, je souhaite une réponse à la question suivante =que est la nature chimique de peptidoglycane?
It's so clear to understand sir tq u and want to know what book u have used is it voet book of pdf it is pls reply sir
I think it is lehninger
one question?? during biosynthesis UDP- NAM is attached to pentapeptide having 5 amino acids so if one amino acid is removed four will remain, here we have L-al, Glu, lys and D-ala, if D-ala is removed after crosslinking then it will left with only three amino acids. m I missing something. ???
human being ok initially you have 5 anino acids including 2 D-ala’s. One D-ala will get cleaved off leaving the other D-ala free with a carboxyl group with then would like to M-DAP (I hope i am right I am still learning this)
Can u please make a new video of this, as this is 10 ys old video and you are stammering a lot . Also didn't really understood the concept well . Please make a new video because now u just teach so perfectly .
Will do that
Is pentaglycin bridge is present in gram negative bacteria ????
Plz reply fast
Thanks
Shukriya💜
You're welcome
Thanks for the explanation ...but if I may, I have e little suggestion: u dont have to use so many unnessary word that makes it anoying sometimes...thnx 😊
+ada shehaj I used to say that. Check out my new videos. I have worked on that part
@@shomusbiologyofficial One question sir, this is one peptidoglycan layer - but is it conected with upper and lower ones? Lets say this is one paper (what you explained), but how is pile of papers connected? Thank you very much! :)
Same question 😩💔
Thank you soo much sir.. sir, can you provide the book pdf?
Sorry I don't have that now
Keep going
Thank you
Tnx sir
You're welcome
Nice work! Foreign accents usually piss me off, but your clear, concise explanation totally cancelled out my racism. Thanks!
Robert Bender nigga you racist AF
Ha! Funny how your accents piss us off more thanks to your unnecessary rolls and omits. We're the ones keeping it real here lmao.
Also, nice work with YOUR grammar :)
Please.....explain again by using board.....
I will later
My mam send me this🙂
All the best
a..a...a...a.....a.....a....
just horrible
