Thank you! I watched the WHOLE BIO CHEM series. You have taught me so much more in a few hours than what my teacher tried this whole semester long! Your teaching technique is so efficient. You repeat enough for us who are new to this concepts and the clarification and connection to previous lectures make your vids like a unsaturated bilayer! Lots of lateral motion :0 and smooth fluidity! Thank you so much. You are changing the medical field one student at a time. BLESSINGS!
In a few hours? He has 257 videos in the biochem playlist. On average of 10minutes, it comes to around 2570 minutes. Which is about 43 hours. Last semester I had biochem for 14 weeks of 5 hours weekly. 2 of them were seminaries. Which leaves 3 hours in 14 weeks. 30mins of which were breaks. Comes out to 150minutes a week times 14. Which is around 2100 minutes, his biochem course is longer than a semester. They are great videos, but professors do a good job as well.
perfect explanation of how cholesterol regulates membrane fluidity in BOTH directions! Never heard of the lipid raft mechanism before, thank you so much!!
You wouldn't expect to see a trans bond in the membrane, they are not common in nature. If they were though, you would expect it to act like a saturated fat because trans fats do not kink.
A bit confused by the graph. So at high temp, membrane is more fluid? I thought it was the opposite since at high temp, cholesterol prevents cells from becoming too permeable therefore causes the membrane to be less fluid.
Higher temperatures give the phospholipids more kinetic energy, which jiggles them all around, they dont pack so tightly and makes the whole membrane less rigid. I like to imagine the phospholipids as soldiers standing in a row, shoulder to shoulder tightly linking arms. That is at low energy. The line is tight and inflexible. At high energy, maybe their boss is away, ya know, they all chill out a bit, loosen their arms. Hey, they're still in a line, not shoulder to shoulder anymore, but maybe just holding hands nowhere near as rigid as before, and thus the overall rigidity of the line is lower and it can wind and weave.
You deserve a humanitarian award for helping needy students all over the world. Cheers all the way from Saudi Arabia.
I found your video on Pronto Therapy Folio - there are many awesome videos there that will help out
I love him. he is actually my Teacher

You're my hero. I love the pictures and pitch that you use to explain all of your videos! Thank you so much!
+Ashantii Bernateau Thanks Ashantii! Appreciate that

Superb, clear, and lucid -- a breath of fresh air from the absolutely abysmal instruction I had from tenured professors during my time in university!
you are incredible.... u should be paid millions....
Thank you so much professor for these great lectures. I really appreciated your effort.
I was smiling through the entire lecture. You described it sooo perfectly 😭
Great sir . Your teaching gives crystal clear idea .
I m u r studient from india .
Indians hit likes here .
You're such an amazing teacher! Love your lectures. Keep making videos and helping students to understand cell biology!!!!
your lectures are very detailed and very nicely organised.thank you
THANK YOU X1000000000, your videos are flawless. Greetings from South Africa.
I would pay you to teach me. My teacher is depressing
Thank you so much, your biochem playlist has helped me so much this semester extremely grateful
The important thing the books even Doesn't explain is the REASON why on increasing this, this decreases
Thank you very much,you literally saved me from failing
1. What is the role of cholesterol in the plasma membrane?
Decreasing membrane fluidity at high temperature
It decreeases movement of phospholipids
thanks for all the help!
11:56 role of cholestrol
Thank you so so much, your lectures in different topics are a real help to me. thank you
excellent
Thank you Sir.
This is easy to understand.
Adv 9th grade bio struggles thx for this vid
Hi,
Is it correct to say that double bonds reduces the number of points of contact between adjacent fatty acids?
THANK YOU SO MUCH
What forces hold the lipids if it not covalent bonds?
Good day! May I ask if hydrophilic head of lipids attracts hydrophobic ends of cholesterol? thanks
Hey +AK Lecture! Great video.
You are great thank you
thnx a lot sir. you shouls start online coching for difrrent entrance test
What about trans double bond, how do they effect membrane fluidity?
You wouldn't expect to see a trans bond in the membrane, they are not common in nature. If they were though, you would expect it to act like a saturated fat because trans fats do not kink.

Please can u give me pdf please 🙏🙏
My micro/cell bio teacher dont even teach. Get into groups and teach each other what you read is not a good enough strategy i dont think.

Guys do u have pdf
Ok
