I never comment on RUclips 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
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 RUclips will change the world one day. Thanks again to you and your team.
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!
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. 👏👏👏🙏
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!
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..
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.
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
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
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
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
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????🤔🤔🤔
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?
"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.
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
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
Hello dirty medicine , can you add the slides file you explain to the video description and it will be useful to me Thank you for the nice job you do and best wishes.
@@olivermfluni4973still using this video up till now. And I must say this is one of the funniest and at the same time realistic comments ever seen😂😂😂. Bro you looked into the future
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?
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.
Why Medium chain Fatty Acyl CoA dehydrogenase deficiency result in Non Ketosis what about Long Chain Fatty acyl CoA Dehydrogenase will not it convert substrate to Acetyl coA and then Following Ketone bodies????????
I never comment on RUclips 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
Shit, he does a better job than the professors that are PAID TO TEACH US.
Your honestly a life savour a 25minute video summarized a 100 lecture slides thank you so much
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!
He makes mega $$$$ from the 30 ads in this video

You are simply AWESOME 👏🏻.
I never fully understand this concepts.
Now- everything understood and condensed in my brain.
Thanks a lot.
I seriously can't thank you enough! you're a lifesaver Dirty
Please never stop making videos you're literally saving lives out here
These biochemistry videos are all you need to pass Step 1 (better than Turco/BnB/Lecturio/Kaplan/Sketchy/Pixorize)
finally understood what I was reading after watching this vid! Thanks! Simple explanation, fast and AWESOME!
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..
Your mnemonics are clever and helpful, even though you say they're stupid.
Amaizing video..
U simplify difficult things and make it easy for us to understand...
Best biochem mentor..

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!!!!
I rarely leave comments but this was extremely helpful and had to say THANK YOU
Very helpful. Simplifies complex concepts so well. Thank you so much sir. You just saved me going through thousands of lecture slides
lost for words. thank you so much, from the bottom of my heart.
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
No words to explain how perfect your videos are🔥
Thank you so much 😀

You are the best I was struggling with this topic 😭 may god bless you ❤
dr ryan is quaking... excellent job
This channel is undersubscribed. These videos are awesome.
Thanks! Please share with friends, colleagues, etc. Would love more subscribers
Brilliant. 100% pure talent.
Thank you sooo very much for the most explanatory and easiest way of learning videos. I’m learning much more than any other resources 👌👌👌💐
Really comprehensive and precise lecture ❤
So excellent.

@@deadricchampion6856 FA says hypoketotic for both so just go with that
perfect for my shelf exam form biochemistry. Thank you tons!!!!!!!!!!!!!!!!!
As clear as day now. Many thanks
Thanks for the fantastic channel
just a simple mistake in (MCAD deficiency) is it actually hypoketotic hypoglycemia the same as carntine deficiency
Dude, your videos are saving my butt. I'm having to cram and these videos are coming in clutch!
Thanks a lot for this well explaining! .. thanks also to my senior for advising me to watch this amazing video
I appreciate the time you took to make this-make sense! thank you!!
Smart presentation as always.
The best educational videos
Tanks alot learning from Nigeria got an A in the course tanks
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????🤔🤔🤔
This is so enjoyable and understandable
You’re just extraordinary
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?
i am confuse also, is Ketotic of non Ketotic?
Amazing explanation!
very concise explanation!
Love your expression "long amount" (length, quantity) !!
The whole video is extremely high yield point
This is exactly what I needed
SOOO FREAKING GREAT!!! Love ur explanations! THANK YOU! SO helpful for my STEP prep rn
you are amazing, Dirty Medicine.
god i hate that i have to learn this in medical school, but i appreacite your content making it bearable and fun.
"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.
Unreal! Thanks so much!
Thanks 👍 for ur videos but what of the main pathway of lipolysis
you're LEGENDARY!
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
idk how high yield this is but the carnitine system is only used by FA with 14-22 carbons
Thank you Dirty
You are amazing!!
Please add this to the biochemistry playlist
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
That’s what he said. ‘Non-ketonic’ meaning hypoketonic
Actually, according to AMBOSS, all 3 types + Long Chain Hydroxyl Acyl-CoA synthase deficiency can lead to Hypoketotic hypoglycemia
Nice job
What if there's 13 carbon?
Please what is produced during incomplete oxidation of fatty acid?
Thank you very much! This video is very helpful
Hello dirty medicine , can you add the slides file you explain to the video description and it will be useful to me
Thank you for the nice job you do and best wishes.
My heroooooo
8 people must've accidentally hit the dislike button on their way over to the like button, cuz these videos are awesome
No they are the textbook printers who can see that a only a short/medium time remains for them to be relevant.
@@olivermfluni4973still using this video up till now. And I must say this is one of the funniest and at the same time realistic comments ever seen😂😂😂. Bro you looked into the future
love you, thanks
In medium chain Acyl CoA Dehydrogenase deficiency, isn't it HYPOketotic Hypoglycemia, instead of NON-KETOTIC? First Aid says Hypo
Noticed this too
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?
They both show no ketones. Hypoketosis = no ketones
@@thsmusicboy how do we differentiate between both clinically?
Bro You are the best
Why do you make a distinction between non-ketotic and hypo-ketotic? In both instances, ketones cannot be produced. Thanks!
Just awesome!
Thank you so much for this❤️
Maybe a dumb question, hypoketotic vs non-ketotic? hypo ketones are low, but still deteactable? non, they're undetectable?
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.
Why just first aid say MCAD defficiency is hypoketotic hypoglycaemia?
Glycolysis link please am unable to search it. BTW you are awesome
how does systemic primary carnitine deficiency lead directly to hypoglycemia?
I didn’t hear you mention the role of Carnitine Acyl Translocase (CACT) in the carnitinie shuttle system?Is it to be ignored?
Why Medium chain Fatty Acyl CoA dehydrogenase deficiency result in Non Ketosis what about Long Chain Fatty acyl CoA Dehydrogenase will not it convert substrate to Acetyl coA and then Following Ketone bodies????????
Nice video 👍
Thank you!
Thank you sir
Very helpful !!! Thanks a lot! 👍
i love your videos!!!
thank you
Good very good
Amazing 👏 🙀
this is so great
God bless you!
Thank you----!
Are CAT2 deficiency and CPTII deficiency the same?
But why does medium chain acyl co DH deffiency cause hyperammonemia?
Anyone know what the difference between non-ketotic and hypoketotic hypoglycemia is? Asking for a friend...
Thanks!👏
Thank you for your videos dirty!
is there no such thing as a 13 carbon fatty acid then?
That's fantastic
Does beta oxidation of fatty acids occur strictly in the liver and nowhere else in the body?
