Phospholipids: types, structure and function

[@JoaosLab]

Hi everyone! Thank you so much for watching the video! 😊Just wanted let you know that a mistake slipped through and I would like to rectify it: at 01:18 I say "phosphorus MOLECULE surrounded by 4 oxygen MOLECULES", should be ""phosphorus ATOM surrounded by 4 oxygen ATOMS". As soon as I have a chance, I will republish the video with the correction, but just wanted to let you know, so it doesn't cause any confusion.

[@harry_1947]

ok... thanks for letting us know... and good explanation...

[@NerdNeonate]

WOW, very clear and understandable way of explaining.

😊 namaste 🙏, thank you so much for this video. Please make a video explaining the role of different types of Membrane lipids.

[@JoaosLab]

Thank you so much for the suggestion! We will write it down. We will do our best to cover it on a future video. 🙌

[@mahaalhamed-v8z]

thank you sir u are the best teacher tomorrow i have bio exam 😊

[@JoaosLab]

Oh thank you so much! I hope your exam went well! 🙌

[@KhalidAlkharji-u3h]

lol I'm in the exact same position rn

[@houssienalaa6700]

Thx u helped me alot

hello, you said sphingophospholipids have sphingosine backbone. Example is sphingomyelin. But at 2:22 in structure of sphingomyelin it is displayed with GLYCEROL backbone...

[@isaacsagoe9446]

I want more on this

[@himalaydebsourav]

excellent illustration, May I know how do you make such eye soothing videos?

[@JoaosLab]

Thank you so much! We mainly use After Effects to create the visuals. 😊

[@PeterInnocent-p2c]

Thanks so much

love your videos always, the use of humour and great animations are literally on spot!! i still have a confusion regarding phospholipids coming from a mcq from 9700 biology, the question itself messed with my mind, "What causes the phosphate heads of phospholipids to become polar?" the answer was The phosphate heads become ionised in water. i dont genuinely get it though, do the heads not already contain a phosphate group which has a charge thus is polar? would be really grateful if you could clarify :)

[@JoaosLab]

So glad to hear! ❤ To answer your questions: Phosphate heads of phospholipids are already polar due to the negatively charged phosphate group. However, when they are in water, which is a polar solvent, these heads become ionized, enhancing their polarity. This means that the interaction between the water molecules and the phosphate heads makes them even more hydrophilic (water-attracting). So, the heads are inherently polar, but their interaction with water further increases this polarity, making them more reactive in a water-based environment. The answer to the MCQ refers to this process of ionization in water, which strengthens the polarity of the phosphate heads.

if it is not personal what kind of software you are using for creating clipart vectors in the video. They look very unique!

[@JoaosLab]

Thank you! :) We use mainly photoshop and adobe illustrator.

i was laughing hard when he say Get your mind out of the guiter 🤣🤣............ btw good explanation 😍😍

[@JoaosLab]

Glad you liked it 😊❤😂

[@AliHassan-yg3tv]

Amazing 👌

[@JoaosLab]

Thank you! 😊

[@ashleymparutsa5793]

Great explanation. What kind of software did you use to make the video.

[@JoaosLab]

Thank you! 😊 We mainly use AE's for the animations.

[@MariannaTriana]

Thanks for your video it was very helpful and i was wondering if you offer more help or tutoring because I have questions to ask you.

[@JoaosLab]

At the moment, we don't have a tutoring service. That's something we could look into in the future. In the meantime, feel free to ask any question. I'll do my best to answer. 😊

[@MariannaTriana]

@@JoaosLab thanks for your response It is because I'm studying to become a veterinarian and I'm taking biochem as a course but in Spanish and I'm trying my best to understand but I feel that I can't do it or that the course is hard on me and by any chance do you know about someone else who can help me.

[@JoaosLab]

@@MariannaTriana Unfortunately, I do not know anyone who offers tutoring services in Biochem. :( If I spot someone, I am happy to reach out to you via this comment.

[@farhatbano8084]

Keep it up

[@JoaosLab]

Will do! Thank you for your support!

[@TamNguyen-qg9uy]

what kind the bond between two phospholipids on a row ?

[@JoaosLab]

Phospholipids in a row primarily interact through non-covalent forces. Hydrophobic interactions cause the fatty acid tails to pack closely in the membrane's interior, forming a hydrophobic core. Van der Waals forces stabilize these packed tails. The polar head groups can form hydrogen bonds with water and other polar molecules, while charged head groups engage in electrostatic interactions with surrounding ions. These combined interactions ensure the structural integrity and fluidity of the phospholipid bilayer, crucial for its role as a cellular barrier and medium for various cellular processes. I hope this answers your question! 😊

[@khanbaloch9639]

Good🎉

[@JoaosLab]

Thank you!

[@sveaerichsen5526]

isn´t sphingosin hydrophobic? Why is it in the head then? Because the head is always hydrophilic

[@JoaosLab]

An important feature of sphingosine is that it is amphiphilic due to a hydrophobic alkyl chain and a hydrophilic headgroup rich in polar groups (OH and NH2).

[@neetlearning123]

Wow

[@Pawan_013]

The phosphate group should rather be : "A central phosphorus ATOM surrounded by 4 oxygen ATOMS".

[@JoaosLab]

You are absolutely correct! That was definitely a slip of the pen. Thanks for bringing this up! 😊

[@nazrawikoko]

Uhhhh
