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

[@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!

[@DrRuslanaBorysenko]

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

[@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.

[@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!!!!

[@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

[@johannahaso8050]

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

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

[@mr.medtech731]

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

[@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. 👏👏👏🙏

[@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.

[@flatif23]

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

[@noelamassawe1602]

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

[@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

[@SoulReviving786]

Really comprehensive and precise lecture ❤

[@prakharprateek1643]

This is exactly what I needed

[@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..

[@jaikumar1524]

[@oglooshartoszalgi4767]

love you, thanks

[@ha00727]

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

[@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

[@beyasha]

Thanks a lot!!!

this is so great

[@simonbayuo5484]

That's fantastic

[@wicterwterr4245]

Thank you----!

[@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

[@archangel80303]

I didn’t hear you mention the role of Carnitine Acyl Translocase (CACT) in the carnitinie shuttle system?Is it to be ignored?

[@singhrajveer2008]

Thank you

[@khadijahussein8396]

thank you

[@mariamaibrahim2941]

Amazing 👏 🙀

[@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

[@shanewaldrop3513]

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

[@dachipavliashvili5588]

ty very much :)

[@Esayas-M]

Thank you sir

[@rosadiaz2925]

The whole video is extremely high yield point

[@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?

[@carolnewme3106]

I love you seriously

[@user-vr1id8tr9v]

Thanks 👍 for ur videos but what of the main pathway of lipolysis

[@ShahadAljuhani-nd8ep]

Omg thank sm

[@rkotak7853]

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

[@SRoseFV]

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

[@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.

[@yashpawate1306]

Wouldnt you get hypoketotic hypoglycemia in MCAD because you arent making acetyl-CoA and hence cant make ketone body synthesis?

[@agh6452]

You said that the fatty acid will diffuse to mitochondrial membrane and then it will need carnitine to move into mitochondria so at the point of carnitine deficiency you are saying that there is no carnitine to take the fatty acid in mitochondrial membrane 🤔🤔 I heard like that

[@PIPSCHTICK]

What if there's 13 carbon?

[@user-rd1qo4cb2l]

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

[@jcleach2764]

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

[@elokacharles2142]

Please what is produced during incomplete oxidation of fatty acid?

[@mikelalbisu2304]

But why does medium chain acyl co DH deffiency cause hyperammonemia?

[@karansharma2449]

❤

[@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????🤔🤔🤔

[@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

[@saamariumsans6837]

@@thsmusicboy how do we differentiate between both clinically?

[@alexserrano2599]

Does beta oxidation of fatty acids occur strictly in the liver and nowhere else in the body?
