Lipid Biochemistry (EVERYTHING YOU NEED TO KNOW MCAT) glycerol, phospholipid, sphingosine, ceramide

[@chrissysoss]

I discovered your channel about a month before taking the MCAT, and I am so so glad I did! Your videos are so helpful, I don't think I would have done nearly as well as I did without them. I can only imagine how much time you must've spent making these videos, so from the bottom of my heart thank you for all your hard work! I hope medical school is treating you well.

[@ibtihagalnooh4078]

Hello sorry to ask you but I will be taking the mcat in two months and I super worried do you recommend any study strategy or any advise for me please let me know.

[@chrissysoss]

@@ibtihagalnooh4078 I would recommend checking out r/mcat on reddit, there's a ton of helpful study tips!

[@bibi-mk3xq]

I really like the fact that u show us the bigger picture and give us a visual map to see how pathways are connected to each other without making it too complex

[@imosdefinite]

this guy making so many doctors through these videos! thank you!

[@Anastayija]

Amazing explanation! Far the best I have seen so far! Short and on point! Excellent!

[@cheesuscrust5391]

you sir have just saved me hours of headaches dealing with lipids. THANK YOU

[@MrTimmyC86]

Very high energy which I found a bit annoying at first, but by the end of the video I understood my entire anki deck on lipids that has been confusing me for DAYS. Well done, sir. Well done. Lipids have now have a legit connection to the other concepts in my biochemistry/metabolism semantic network Keep doing you my man. And thank you!

[@IdontKnow-gm7eu]

Ehhh, I found it funny if anything. It makes Biochemistry more interesting and a welcome change from my monotone teacher.

[@catherineanz3333]

thank you so much for taking the time to make these videos! they're so helpful!

[@Mslilli1000]

Wow! absolutely amazing! I got how this works now! Thank you very much!

[@x94mim]

This is so incredibly valuable and insightful. It adds much needed depth to some of the review books. Understanding how the various lipids are formed via the mechanisms makes it easier to remember content about lipids!

Excellent review, thank you.

Keep up the good work🙏🏾🙏🏾

You are a lifesaver sir!!

bless your soul wow

[@jasminesturn]

This is EXACTLY what I needed for the MCAT. THANK YOU x A MILLION

[@shanarobinson7672]

How did it go? The MCAT? Did these videos help?

[@jasminesturn]

@@shanarobinson7672 I think it went well!!!! Scores come out June 27 so I’ll update u then🫣🫣

[@PAUTNETER]

@@jasminesturn Wishing you the best goddess! I hope you got it!!!

You are amazing thank you so much

[@alexakalennon]

That was awesome

[@cliente8438]

Right, on brother.

[@juniorcyans2988]

I don’t understand what should be done to make a leaving group?

[@Tk-vf4qr]

AMAZING AMAZING AMAZING

[@yousefalheraijy7198]

11:16 Before making a sphingolipid, wouldn't the fatty acid be activated as a fatty-acyl CoA?

[@ryanisber2353]

I love these

[@karenweng9091]

YOU are the GOAT

[@josephkass477]

you are a beautiful man. thank you.

[@danielpugh2660]

You can add it!

[@Cosmwick]

literally used this video for a game called the password game, thanks

[@abunusayba1]

can tyrosine and threonine be also added to it the same way as serine since they both have an alcohol group attached to them?

[@dasiathomas6531]

Yes, as long as there is an hydroxyl group you can add it.

[@bp-dw4rp]

GANG GANG AYEEE TYSM!!!

[@zakmatew]

Best!!!

[@JonahSteps]

in mechanism 1, you say there is released a OH. However, in my class they say that this mechanism produces H20. What am I missing?

[@sciencesimplified3890]

So what I meant is that the -OH on the original compound is lost…. But that OH gets an added H+ and leaves as a water molecule… so to clarify the -OH on the original molecule is lost as a water molecule

[@mysteryman595]

Man, I love you

[@manassehagbeshie1574]

Take your time please

[@xthatswhatsuppx9772]

Can someone help! At 1:35, he adds electrons to the OH group so that it can leave. However, I though OH- was a bad leaving group so how does that work??

[@sciencesimplified3890]

There are biological enzymes that stabilize the OH, therefore facilitating the OH to leave as a leaving group… a common example is an enzyme protonates OH so it can leave as H2O

[@xthatswhatsuppx9772]

​@@sciencesimplified3890 I apologize as I realize you answered this in a different comment!! But thank you so much for such a quick response!

[@kashishchak5706]

14:20 time stamp. The carbohydrate has a positive formal on the oxygen and I'm guessing delta positive on the carbon. Shouldn't O- as an nucleophile attack the formal positive charge O, instead of the carbon. I'm assuming there is no serious steric hinderance. Can anyone explain why it attacks C and not O?

[@sciencesimplified3890]

Attacking the carbon push’s the double bond Pi electrons into the oxygen, effectively removing the +1 charge on oxygen.

[@joeamrine7450]

Also, keep in mind that generally speaking, biological enzymes catalyze all these reactions, which allow formation of several highly unstable intermediates.

[@kashishchak5706]

Makes sense! Thank you for the explanation.@@sciencesimplified3890

[@kashishchak5706]

Whoops! I assumed that it had to be stable intermediates. Thank you :) @@joeamrine7450

[@eseasoro7251]

So Cholesterol is made from glucose interesting . So carbohydrates are building block of lipids hmm

[@ritabessa1567]

This video is very well explained, however i think there is a better way to show the slides without having to pick the "layers". Thanks!
