Literally the best explanation on this topic I've ever come across! You are the best. I'm sitting here in awe at how much clarity I've gained from this one video :o Thank you so much DM!
sir I don’t know what this world has done to deserve you , you are amazing teacher. you are doing a great job ,keep going and stay blessed. i almost watched your each and every video and every single video is amazing thank you so much sir !
You are a homie and a half, great way of re reviewing all of this. Myself and everyone else who hasnt really should get on donating to you and this channel.
A 4th way you can form ketone bodies is by following the KETO Diet! haha. But I suppose this can go under starvation because the idea is to deprive your body from Carbs so insulin stays low.
@@whitelion124 I would also think that ETC Complex 2 is an enzyme on TCA Cycle (Succinyl DH). So inhibiting TCA cycle directly inhibits ETC. So they can't use it even though there's a high amount of NADH
I would be very interested in references on this. It seems not quite right in that 1. OAA scan be supplied from Asp via transamination. 2. Acetyl-CoA is an activator of pyruvate carboxylase which will increase OAA when needed for TCA cycle. No? Also, liver is active in gluconeogenesis but liver doesn’t use ketone bodies. Not a challenge but what about these points?
Help me understand the process of alcoholism and TCA cycle shuts down? What happens when that person eats sugar? Where does the sugar go? Stored in the liver and not the cells? Or the sugar doesn’t produce atp energy for the alcoholic? Is seems like the solution would be to take mct oil and exogenous ketones? This is good stuff?? This video has me really curious as to the pathway?
Ketones get converted back to acetyl-coA when they reach their destination. How are ketones then helping to produce energy if the TCA cycle can't continue because of the lack of oxaloacetat? Why form ketones because of oxaloacetate depletion if you need oxaloacetate to gain energy from ketones?
To clarify, the body's primary preference is to eliminate glucose as soon as possible. Before the advent of highly processed foods and the introduction of sugar, mankind relied on burning ketones for energy. It is important to remember that the body will make every effort to get rid of glucose due to its potential harm.
Can Someone Please Clear This Doubt For ME.. Why does buildup of acetyl CoA from failure of TCA cycle shunt towards Ketones and not gluconeogenesis? Acetyl CoA stimulates pyruvate carboxylase right
I'm late to the video but just in case you're still active and replying, I have a question. Is acetylacetyl CoA the same as acetoacetyl CoA? That's what I'm seeing in my textbook
The high-level overview of the mnemonics doesn’t seem helpful to improving my conceptual understanding of how things actually work. Rather, it seems more like a memorization technique to pass a quiz. I’m just trying to understand how things work. I am not a medical student because I don’t accord with the Sociopolitical ideations of modern college and medical school. Aside: describing things that are important as “high-yield“ is silly and somewhat distracting. I appreciate the effort you put into this. I just don’t completely understand it. The subject matter requires deeper and more involved discussion than a 21 minute video. Do you have more videos to breakdown each of these components in slightly more detail? It would be nice to start with a high-level overview, then go into deeper discussion of bio chemical and physiological pathways, and then draw those pathways back into the high-level topic of discussion. Thank you.
Can someone please explain how it is possible to use Ketones as an energy source? If it is actually formed due to oxaloacetate depletion or a NAD/NADH disbalance and if it's degradation would form acetyl CoA as a final product, how would it produce energy without undergoing TCA cycle?
He states when things are depleted and no oxaloacetate, our body will produce ketones as a result of a loss of ATP. The TCA cycle will not commence. Ketones will be the new source of energy.
That TCA cycle takes energy to go thru the whole process? Thus more energy short cut with ketones? Ketones also release less free radicals, so less Glutathione needed?
@@sgill4833I don’t think so, cholesterol biosynthesis is a separate pathway from ketone metabolism. It’s just a coincidence that HMG coA is produced in both pathways
This one truly left me SHOOK. Big brain moment right here

If alcoholic have increase NADH why dont they directly go to ETC?????
Probably because we're in the liver, at least that's my best guess.

THANKS for this!
Thanks for explaining!
Super cool! Super high yield!!!!! 👍
You are the best .. 😮😮

This
Amazinng
u truly saved us
me - 'fasting'
brain - *gimme them ketones*
i need to say this but I LOVE YOU DOC OMGGG YOU HELPED MEEEEE!!!! 🤟🤟🤟 THANK UUUU
Hands down. u r the best! If I was a millinore, i would sponsor ur channel.😅😅
Please explain how ketone synthesis occurs when someone eats low curb high fat diet.
My savior ❤️😍😍😍😍
Amazing video!!!
thank you very very much really you are amazing
Great video for students but why does the body make 3 ketones? Surely one is enough?
😂
I wonder if his other topics are as good as his biochem series?
Please make a video on harmful effects of ketone bodies.

You are the best 😭♥️♥️♥️♥️♥️♥️♥️♥️♥️

So Keto-Diet is ?.. good/bad?

Very well-done 🥰🤩
Did you mean starvation was equal to very low carbohydrate diet?
Yes
If you're NOT DIABETIC ketosis is the preferred fuel of the body. BHB is what you want.
You got a magic ocean potion advertisement on your video. Really pushing the agenda they are.
How is this free :'D Thank you sir!
i gonna give the IFOM exam ...i hope this video helpful for me😍😍
Umakant Shinde Yes , extremely useful for IFOM , I recommend you all the videos for review
Good Luck

acetoacetyl-CoA* but same thing.

You are not starving, you are fasting.
Wait a sec, statins are called hmg-Coa inhibitors. So basically statins will prevent you from building ketones.
Does that mean, byproduct of ketones synthesis is cholesterol? I'm not in medical school. Just learning for personal health.
@@sgill4833I don’t think so, cholesterol biosynthesis is a separate pathway from ketone metabolism. It’s just a coincidence that HMG coA is produced in both pathways
Statins = HMG coA reductase inhibitors
