Fructose Metabolism and Breakdown Pathway: Absorption, Fructolysis, Regulation and Health Impacts
Hey everyone! In this lesson you will learn about the fructose metabolism pathway aka fructolysis, including an in-depth overview of the pathway, how fructose is absorbed in the body, where fructose metabolism occurs in the body, what enzymes are involved in fructose metabolism pathway, and how fructose metabolism contributes to non-alcoholic fatty liver disease, obesity and diabetes.
How does fructolysis, the metabolism of fructose, differ from glycolysis? Fructolysis utilizes specialized enzymes and undergoes significantly less regulation than glycolysis.

Yes that’s great for explain how bad refined fructose is to the body, especially in the form of HFCS (think sweetened cola drinks). But you left out the part of how the gut biome deals with the fibers, polyphenols, antioxidants of the whole apple-think of it as a timed, slow release of fructose and the role of gut bacteria to regulate and actually increase insulin sensitivity… from the whole apple. Having said that consider blueberries, blackberries and especially raspberries - more of that positive benefit but much less fructose than an apple. I’m just saying we need to see this holistically.

in the real facts, considering a western population for instance. The fructose that would lead to the synthesis of TAG would not come from fruits. It would come from sugar, from HFCS (high fructose corn syrup), which the "food" industry or rather the junk industry uses everywhere, right? I am a fruit eater, never eat industrial "junk", live on fruits, vegies, some tofu, a few things like that. Would I be at risk for NAFLD? obesity? diabetes?

I am a Marathoner and have noticed that some of the energy gels for Athletes contain a combinacion of Glucose and Fructose, my question is if once Fructose has reached Acetyl CoA this can enter the Krebs Cycle for ATP production, in other words how would Fructose provide energy for the body. Thank you in advance.

@mariosierra7744 Жыл бұрын

It gets used as energy if eaten while doing some sort of activity, the reason it turns into fatty acid is that, that's how it gets stored. Most people aren't running marathons and are getting their fructose from candy while not being active. So the best use for fructose (coming from a health/performance angle) would be to have it while doing some sort of workout/strenuous activity lasting an hour+ for its help in producing energy quickly. Since your using it theirs nothing to be converted into triglycerides. For everyone else snacking on the body cant regulate or stop its metabolism, so as soon as it goes inside your body, its either used for energy or stored as glycerides

I've read studies that shows it's better to have your post-workout drink be a combination of glucose and fructose. As mentioned in the video, absorption of glucose and fructose from the GI lumen is by different transporter systems (SGLT1 and GLUT5) and each of these transporter systems has a limit to how much they can absorb. By using a combination of 2 different transport systems, your body is able to absorb more total carbohydrates. I still think that under the body condition of blood glucose depletion (post workout), the fructose would be converted to glucose production rather than Acetyl CoA production, at least until your blood glucose is restored. Not an expert though, just my opinion.

Questions: 1) why wouldn't the large amounts of pyruvate formed from sucrose go through standard pyruvate metabolism the same way pyruvate from glucose does? 2) Even if sucrose is regulated upstream, why wouldn't fatty acid synthesis from fructose be regulated by the standard mechanisms of FA synthesis? (E.g. Acetyl-CoA carboxylase). Not all of the Acetyle-CoA has to turn into FA. 3) if excess FA are being synthesized in the cytosol, why wouldn't they just be secreted out into the blood stream? Fatty acids are fat soluble and can pass through the lipid membrane. Thanks

@@joohnnykuz5327 I think the question was in regards to when your body is in a state of starvation or post-workout glycogen depletion. In your opinion under those circumstances, would the fructose still go towards fatty acid synthesis instead of restoring blood glucose levels (which would be low in starvation) and restoring depleted glycogen? Intuitively I would guess that a greater than normal percentage of fructolysis would go toward glycolysis. Would that be correct?

@joohnnykuz5327 Жыл бұрын

@@claykurisaki9758 So in that event it can’t. Fructose CANT be used to synthesize FA because gluconeogenesis will be occurring and this process uptakes crucial elements needed for FA synthesis. Gluconeogenesis will occur when your blood sugar is low and your glycogen stores are depleted. Gluconeogensis needs oxaloacetate to proceed so it takes it up in the liver, and it’s shunted up the gluconeogenesis pathway. This is relevant because acetal coA, from fructose metabolism needs to react with oxaloacetate and cintrate synthase to create citrate to transport acetal coa out of the mitochondria of the hepatocytes(liver cells) and into the cytosol where fatty acid synthesis can occur. The fructose will undergo fructolysis, which ends at the creation of DHAP and GA3P, which is the step of glycosides after fructose 1,6BP. This part I’m not exactly sure but This fructose can either become pyruvate which can be used to synthesize glucose, via gluconeogenesis. Or DHAP and GA3P can be shunted into gluconeogenesis

Good but this is not entirely accurate. The reason fructose (F) can be a rapid source of fat is not because of the conversion to acetyl-CoA. The real difference between F and glucose (G) is in the kinetics. It is important to recognize that both pathways wind up with the triose phosphates (Ga-3-P and DHAP). Fructokinase reaction is very fast and the glyceraldehyde kinase is irreversible. So if F is very high that will be converted to DHAP and then to glycerol-3-P. The FA comes mostly from re-cycled fat. We offered a perspective on where F really fits in. (Feinman & Fine, Nutrition & Metabolism). Important to remember that as much as 50 % of F can be converted to G so you have to be careful about details.

GI stands for Glycemic Index. It measures the amount of Glucose in the blood. Fructose is not Glucose so it won't show on the GI. This does not mean that Fructose isn't dangerous. In fact, the issue is exactly that Fructose metabolism is more uncontrolled than Glucose metabolism that makes it so comparatively dangerous.

Glucose metabolism is regulated because glycolysis does not progress if the cell is in an energy surplus state (high ATP to AMP ratio and high citrate content) because citrate and ATP inhibit PFK-1. The result of this regulation is that the excess Glucose-6-Phosphate is directed towards glycogen synthesis.

So the very end of this video highlights the mechanism by which all that unneeded fructose is shunted into fat around your liver and all over, ultimately interfering with other metabolic activities and resulting in obesity and diabetes. The fructose is largely coming from sugar. Your body manages the glucose but not the fructose. Cut out the sugar, go keto / IF for three or four months. You will be amazed but it is not easy to get started. Make yourself go two weeks and the rest of the three months will be a snap. Then check in with yourself and see how you feel.
