Fatty Acid (Beta) Oxidation

[@ramitek]

I never comment on KZbin videos but this channel is phenomenal. Honestly, he does a better job then the paid subscription services I use to prepare for boards. I appreciate you sir

[@asdfjklasdfjkl408]

Shit, he does a better job than the professors that are PAID TO TEACH US.

[@ramayabowen294]

Your honestly a life savour a 25minute video summarized a 100 lecture slides thank you so much

[@hebabazina7265]

Awesome explanation!! Never seen such a kind-hearted person who's willing to give his time for free just to spread knowledge!! I salut u for it!

[@michaelrowland-us3he]

He makes mega $$$$ from the 30 ads in this video

[@justino4084]

Legend. Thank you so much for your videos. You, the organic chemistry tutor, and khan academy are the first three creators/teachers I will give money to just as a way of saying thank you for helping me achieve my goals in university and beyond. Having high quality upper level education available for free on KZbin will change the world one day. Thanks again to you and your team.

[@existenciaintegrativa]

You are highly capable of learning, memorizing and teaching. I could understand fatty acid oxidation as you mentioned the focus on long chain fatty acids. Congratulations for your contributions to us all. From Brazil, thank you. 👏👏👏🙏

[@sarinamoser5787]

Honestly, your chanell helped so much with my exam prep for my nutrition bioscience bachelor. Everything is boiled down to the important information. How you explain and display topics just clicks for me!

[@tasneemkeddo1219]

very helpful videos! Thank you very much, I am studying for the MCAT to take it next month and your videos are saving me I never understood biochem the way I do now! The best biochem pathway videos, are simplified and gives the main point and are not overwhelming!

[@reemfarhat7242]

I seriously can't thank you enough! you're a lifesaver Dirty

[@princessbaby6279]

Please never stop making videos you're literally saving lives out here

[@DrRuslanaBorysenko]

You are simply AWESOME 👏🏻. I never fully understand this concepts. Now- everything understood and condensed in my brain. Thanks a lot.

[@oliviabunbury7025]

I swear Im sooooooo upset with myself that I didn't find your channel sooner. I have exams in less than 3 weeks and Im only now learning this concept properly looolllll Better late than never though. THANKS MUCHHHHH

[@johannahaso8050]

finally understood what I was reading after watching this vid! Thanks! Simple explanation, fast and AWESOME!

[@Dolphin_457]

This is a great educational video for those who are on Ketogenic lifestyle and OMAD/Intermittent Fasting...because, most of those people on Ketogenic lifestyle and IF, consume MCT oil in their coffee, medium chained triglycerides and grass-fed ghee or butter--long chain fatty acids..

[@bpoole99251]

Hey @Dirty Medicine one thing I think would be helpful in future videos is after going over a topic. Immediately do a couple of questions pertaining to said just covered material. Or provide a hotlink to one of your high yield questions that pertains to the just covered material. As always great job.

[@bronxbomma718]

These biochemistry videos are all you need to pass Step 1 (better than Turco/BnB/Lecturio/Kaplan/Sketchy/Pixorize)

[@guerra017]

I rarely leave comments but this was extremely helpful and had to say THANK YOU

[@bonniemaddock6970]

Your channel tells us the essentials of what we need to know. It is definitely my favourite high yield resource i have found. Thankyou so much!!!!

[@akosuabeeko2990]

lost for words. thank you so much, from the bottom of my heart.

[@noelamassawe1602]

Amaizing video.. U simplify difficult things and make it easy for us to understand... Best biochem mentor..

[@chiefdawid2664]

Very helpful. Simplifies complex concepts so well. Thank you so much sir. You just saved me going through thousands of lecture slides

[@Jana-ne6km]

Your mnemonics are clever and helpful, even though you say they're stupid.

[@thegahd]

10:55 it's already in the mitochondria, it just has 2 membranes, so acyl-coa first diffuses through porins and then it's inside. Also you forgot to mention the enzyme Carnitine Acylcarnitine translocase which moves acyl carnitine through the inner membrane, CAT-2 does something else. CAT-2 puts coa back onto the acetyl group and actively transports carnitine back over to the outer membrane of the mitochondria. Otherwise good video

[@shubhadasurve8129]

No words to explain how perfect your videos are🔥

[@DirtyMedicine]

Thank you so much 😀

[@tim_0917]

You are the best I was struggling with this topic 😭 may god bless you ❤

[@mr.medtech731]

Dude, your videos are saving my butt. I'm having to cram and these videos are coming in clutch!

[@agh6452]

Thank you sooo very much for the most explanatory and easiest way of learning videos. I’m learning much more than any other resources 👌👌👌💐

[@rmercer]

This channel is undersubscribed. These videos are awesome.

[@DirtyMedicine]

Thanks! Please share with friends, colleagues, etc. Would love more subscribers

[@fuzzy23-r8t]

I appreciate the time you took to make this-make sense! thank you!!

[@MichaelFenley]

Brilliant. 100% pure talent.

[@yashpawate1306]

perfect for my shelf exam form biochemistry. Thank you tons!!!!!!!!!!!!!!!!!

[@alevelsdemystified3410]

So excellent. couple of things tho in primary carnitine deficiency, the carnitine cannot be taken up by skeletal and cardiac muscle. there is also secondary carnitine deficiency, which is secondary to defects in beta oxidation that lead to a built up of acyl carnitine. This acyl carnitine is lost in the urine... and this leads to a carnitine deficiency. There is also decreased carnitine synthesis in liver disease or in patients using valproic acid (use of this drug reduces renal reabsorption of carnitine) CPT-II deficiency as you mentioned also effects liver and kidney, other than skeletal muscle. but the form that affects the skeletal muscle is most common and severe. Treatment here includes avoidance of fasting use of high carb diet and supplementation with medium chain fatty acids plus following the involvement of fatty acyl coA dehydrogenase. Couple of other enzymes are involved like 2 3 enoyl coA hydratase then 3 hydroxy acyl coA dehydrogenase and 3 ketoacyl coA thiolase. An oxidation then a hydration then another oxidation followed by a cleavage

[@deadricchampion6856]

Hey dude, you seem to know to know your shit. Would you be kind enough to elucidate why MCAD results in NON ketogenic hypoglycemia? like why would it be different from primary carnitine deficiency which is HYPO ketogenic

[@frameshift_mutation]

@@deadricchampion6856 FA says hypoketotic for both so just go with that

[@ibrahimkhoja]

Thanks a lot for this well explaining! .. thanks also to my senior for advising me to watch this amazing video

[@thevegandragon4676]

As clear as day now. Many thanks

[@SoulReviving786]

Really comprehensive and precise lecture ❤

[@ha00727]

Thanks for the fantastic channel just a simple mistake in (MCAD deficiency) is it actually hypoketotic hypoglycemia the same as carntine deficiency

[@CrazedPochama]

[@kayallen7603]

"Starvation" is induced when one hasn't eaten for 12 hours. Which is why NOT snacking after dinner = weight loss, when you skip breakfast and wait to eat until after lunch. There are major health benefits to doing this.

[@DudeWhoSaysDeez]

[@Science.Medicine209]

Dirty I have a question for you. WHY and HOW the fatty Acyl-CO-A crosses freely through the outer membrane without any help but not through the inner membrane????🤔🤔🤔

[@rapiddermreview]

Amazing explanation!

[@poppymooree0759]

Thank you so much for this❤️

[@vaugndevera2337]

So in first aid it says that MCAD is hypoketotic/hypoglycemic but on the video states that MCAD is nonketotic. I just wanted to know how to distinguish between the two?

[@JML0305]

i am confuse also, is Ketotic of non Ketotic?

[@pierce1234567891]

god i hate that i have to learn this in medical school, but i appreacite your content making it bearable and fun.

[@eugeniaagnesrombelayuk1789]

[@RobertoHidalgo-t7b]

Dude i know you are a great person by providing these content but according to Uworld your Disease page has some errors on it please correct it BOTH SYSTEMIC PRIMARY CARNITINE DEFICIENCY AND MEDIUM CHAIN FATTY ACYL COA DEHYDROGENASE DEFICIENCY CAN HAVE HYPOKETOTIC HYPOGLYCEMIA

[@seunesther]

That’s what he said. ‘Non-ketonic’ meaning hypoketonic

[@laythahmed7179]

Actually, according to AMBOSS, all 3 types + Long Chain Hydroxyl Acyl-CoA synthase deficiency can lead to Hypoketotic hypoglycemia

[@rahatullah7783]

You are amazing 🎉❤

[@aprilg5626]

i love your videos!!!

[@shanewaldrop3513]

idk how high yield this is but the carnitine system is only used by FA with 14-22 carbons

Love your videos! thank you so much! Can someone clarify please why in Systemic primary carnitine deficiency you can't get fatty acyl CoA into mitochondrial membrane? I thought it can diffuse through and then use CAT1? :( Brain. Fried.

[@SRoseFV]

Why do you make a distinction between non-ketotic and hypo-ketotic? In both instances, ketones cannot be produced. Thanks!

[@gabrielasuero3430]

In medium chain Acyl CoA Dehydrogenase deficiency, isn't it HYPOketotic Hypoglycemia, instead of NON-KETOTIC? First Aid says Hypo

[@jorge.04]

Noticed this too

[@rumbler0]

Lmao Dirty you said exactly what I've been thinking for all of Dedicated when you were like "the reason why this is high yield is because...well it's just some minutiae you have to memorize" STEP would not be the beast it is if they cut out all the random bullshit

[@BlackSideburns]

why does systemic primary carnitine deficiency show hypoketosis while medium chain fatty acyl coA dehydrogenase deficiency shows no ketones? shouldn't they both show no ketones based on the logic in the pathways shown?

[@thsmusicboy]

They both show no ketones. Hypoketosis = no ketones

[@ant-hw9os]

I don't understand why hypoglycemia occurs? What does it mean when you can't mobilize energy stores because of fatty acyl not being able to be transported, or form acetyl coA?

[@ant-hw9os]

can't we just form glucose thru gluconeogenesis or glycolysis? or is he specifically referring to periods of starvation

[@Doinmabestt]

That’s what I’m thinking too

Maybe a dumb question, hypoketotic vs non-ketotic? hypo ketones are low, but still deteactable? non, they're undetectable?

Glycolysis link please am unable to search it. BTW you are awesome

[@HarpreetKDodd]

In Myopathic Cat-2 and primary acylcarnitine, would the treatment be the same as Medium Chain Fatty acyl-Co Deh. Deficiency? I.e avoid fasting and eat high carbs?

[@PIPSCHTICK]

What if there's 13 carbon?
