Why is the brain dependent on glucose? - Biology Stack Exchange

Web12 Jun 2024 · On a standard diet with ample consumption of carbohydrates, glucose is the default fuel for the brain. As we established, ketones can replace glucose, and a rule of thumb is that every ~1mM of BHB (the main ketone body) can account for 10% of brain metabolism. Again, glucose and/or ketones are used by the mitochondria within brain … Web3 Dec 2024 · Can the brain function on ketones? The short answer: Yes, it can. In fact, the brain can perform quite well running on ketones. When the body is in a state of glucose depletion (during periods of fasting, during intense exercise, or when following a ketogenic diet), it can run on ketones 2. schwalbe billy bonkers 26x2.1

Which Is a Better ‘Fuel for the Brain’: Ketones or Sugar?

The three ketone bodies, each synthesized from acetyl-CoA molecules, are: • Acetoacetate, which can be converted by the liver into β-hydroxybutyrate, or spontaneously turn into acetone. Most acetoacetate is reduced to beta-hydroxybutyrate, which serves to additionally ferry reducing electrons to the tissues, especially the brain, where they are stripped back off and used for metabolism. Given the clinical application of ketogenic diets to treat refractory epilepsy, it would be logical to expect that KBs could exert their therapeutic effect by directly reducing neuronal firing rates (Figure 1). In this regard, one of the very first studies on brain metabolism and the effect of ketogenic diets showed that shifting … See more Ketone bodies (KBs) were long considered mere by-products of fatty acid breakdown that increase during fasting and other situations of glucose shortage, which can be physiological, including extenuating exercise, or … See more Before dissecting the biological effects of KBs, it is important to understand the basic biological and physiological context of KBs. For a comprehensive review on ketone body synthesis, release, uptake, and utilization, the … See more As discussed above, KBs can elicit immediate responses by modulating ion channels, as well as long-term adaptive responses, by … See more Among other biological functions, compelling evidence has shown that KBs have the ability to regulate gene expression (Figure 2).
