You forgot to mention that fluidity of the membrane depends on the cis and trans of unsaturated fatty acid tail. If you have a trans unsaturated fatty acid tail, fluidity decreases because the space between phospholipids are tightly packed. On the other hand, if you have cis unsaturated fatty acid tail, the fluidity increases because the phospholipids are less packed.
THANK YOU!! This video made me wonder how things can be made simple to comprehend , unlike the complicated version we find in our textbook or in college lectures.
You should mention that how cholesterol affects fluidity also depends on the number of saturated and unsaturated fatty acids. If the membrane consists mostly of saturated fatty acids with straight carbon chains, cholesterol will push them further apart from each other, increasing the fluidity. But if there are many unsaturated fatty acids with bent chains, cholesterol will fill in the gaps between them, making the membrane less fluid.
I couldn't find a paper verifying the research. For example cholesterol uses in the wiki page has a citation need. So can you direct me to a paper that has proven it ?
can you explain the differences between unsaturated FA in affecting the fluidity? I learned that the DHA has the most positive effect on the fluidity whereas the bonds between omega-6's are much tighter. But I would like to understand it better. Why?
Studying this in my Intro to Cell Bio class and the answer is yes--longer chains actually decrease fluidity because there are more interactions between the tails (I think of it as longer tails having more opportunities to be "tangled" and not as mobile!)
thank you very much!that was really helpful😊 actually i was wondering how can membrane proteins affect its fluidity? i really hope you answer me you have a great way to explain 😊thank you
So a diet rich in saturated fats is a poor one, better still consume more unsaturated fats, oh those clever keto zealots, I pity their ignorance and arrogance.
Well it depends on where the saturated fatty acids end up. If they primarily get metabolized through beta oxidation >> Krebs cycle, then they won’t end up in phospholipids. This idea is just energy balancing and is probably too simplistic. I will continue researching these topics
@@kmcveigh100 The cell membrane prefers polyunsaturated fats, a cell membrane is affected by saturated fat, so it's best to reduce saturated fat in the diet.
Yay! I finally understand how cholesterol affects fluidity! Thank you!

watching this in 2021, no one could have explained it better! thank you so much :)

yeah.. i was waiting for this concept throughout d video. thanks.
Exactly What I was thinking dude
i should pay my propins to you, not my teacher who always tells me "go search"
Pls make more videos like these for Alevel biology...it’s very helpful... thank u
i love you !! thank you, i have a test this evening :)
THANK YOU!! This video made me wonder how things can be made simple to comprehend , unlike the complicated version we find in our textbook or in college lectures.
The only reason I'm passing college...
thank you so much for this. i'm learning about cholesterol and research is what I resort to during this time. thank you!
Explained superbly... Awesome sir
Wow that was so helpful.
amazing and clear explanation sir
Thank you for this wonder full session 🎉🎉
Merciii❤
ABSOLUTE LEGEND !!!
what is the purpose of the fluidity??
THANKS SO MUCHH
you do great work for facilitate the Science
Thank u so much. This was informative...
Really helpful video
Thankyou so much for this explanation.
This help him to understand! Thank you
It's wonderful
Thanks
Thank you so much
Thank you ❤

Thank You Very Much Sir I Learnt a Lot From This ..
so then what is the main function of cholesterol molecules in the plasma membrane would it be that it helps maintain fluidity
Cholesterol has one more function. It enhances the permeability barrier properties of the lipid bilayer.

excellent explaination. thanks.
Thank you so much
It would be really helpful 🙏
thanks man !
THANK YOU!!!! YOU SAVED MY MARK
That was very helpful. Thank u
Thank you!
Hi, could you tell me what software or tablet you used for writing/drawing during your lecture? Thanks.
this really helped me understand this concept
thank you!! super helpful
thanks!
thank youuu! :) that was really helpful
You the best
Does chain length have an effect on the fluidity of the cell membrane?
Studying this in my Intro to Cell Bio class and the answer is yes--longer chains actually decrease fluidity because there are more interactions between the tails (I think of it as longer tails having more opportunities to be "tangled" and not as mobile!)
THANKKK YOUUU !!!!
thanks 😊😊
Please give me
relationship between fluidity and viscosity
thank you very much!that was really helpful😊 actually i was wondering how can membrane proteins affect its fluidity? i really hope you answer me you have a great way to explain 😊thank you
iss 09
thaaaaaaaaaaaaaaaaaaaaaaaank sooooooooooooo much
That was really helpful man but I wonder why cell membrane acts as a fluid ?
The fluidity of Cell members depends on:-
1.lipids
2. Proteins
3. Glycoproteins
Cholestrol help keep phospholipids apart as well as together...i can't really get it
What happens if cholesterols are much higher than you need ?
He sounds so sympathetic to the phospholipids 🤣
Like plant cell membrane shows more fluidity than animal's cell membrane at same condition ????
Why i wasn't taught this in high school??
I'm watching this trying to figure out how spike protein get out of the cells. Can anyone lead me the way?
Is cell membrane fluidity the same as cell membrane dynamics?! Gosh am sooo confused 😥
But if we look at human body, temperature should be pretty constant.
So a diet rich in saturated fats is a poor one, better still consume more unsaturated fats, oh those clever keto zealots, I pity their ignorance and arrogance.
saturated fatty acids are non essential fats fora reason, they serve no purpose in the body.
