Editors' Note: Readers are advised that concerns have been raised regarding the methodology and reporting of this clinical trial and an incomplete declaration of competing interests, which are currently being investigated by the Editor-in-Chief. Further editorial action will be taken as appropriate once the investigation into the concerns is complete and all parties have been given an opportunity to respond in full. Fatigue in these patients can last for decades. Here, we examine the use of higher dosage AEO as a medical food to relieve pathological fatigue. At baseline, The main outcome measure was to compare baseline scoring with results at 6 weeks with the Chalder Fatigue Score Likert Scoring versus historical placebo. The hypothesis being tested was formulated prior to data collection. Both physical and mental fatigue were significantly improved over baseline and historical placebo. Here, treatment to normalize metabolism with Anhydrous Enol-Oxaloacetate has for the first time shown improvements in Pathological Fatigue.

The overall reaction, which is spontaneous, may be summarized as:. Thus, brain tissue GOT emerges as a novel target in managing stroke outcomes, oxaloacetate food sources. AC analyzed and interpreted the patient data regarding patient survey responses.

But could there really be a secret to improving our longevity and maintaining vibrant health? Scientists and doctors are finding mounting evidence that might get us one step closer to finding the key to a longer healthier life. What is this secret you ask? A little molecule known as oxaloacetate. Your body is made up of trillions of microscopic cells — all with their own complex structure and function. Your cells can potentially face a barrage of threats that can endanger or even kill them.

Oxaloacetate is a 4 carbon-dicarboxylate, which is an intermediate of the citric acid cycle Krebs cycle or tricarboxylic acid cycle , is involved in energy production within the mitochondria 1. Oxaloacetate is also involved in many biochemical reactions including gluconeogenesis glucose synthesis , the glyoxylate cycle, glyoxylate degradation, anaerobic respiration, the Krebs cycle citric acid cycle , aspartate biosynthesis, and degradation of glutamate see Figure 1 1. It is well established that glutamate acts as an important mediator of neuronal degeneration during cerebral ischemia 2. The systemic administration of oxaloacetate represents a novel neuroprotective strategy to minimize the deleterious effect of glutamate in the brain tissue after ischemic stroke 3. The neuroprotective effect of oxaloacetate is based on the capacity of this molecule to reduce the brain and blood glutamate levels as a result of the activation of the blood-resident enzyme glutamate-oxaloacetate transaminase GOT 4. Oxaloacetic acid is a critical metabolic intermediate and is found within every mitochondrion. Oxaloacetic acid is a small molecule that is highly water soluble, and oral supplementation results in distribution of the compound throughout the body via the bloodstream 5. Once in the body, oxaloacetate the water soluble ion can react in several ways. A highly energy favorable reaction is the conversion of oxaloacetate to L-malate, catalyzed by the enzyme malate dehydrogenase.

Amine-catalyzed decarboxylation of oxaloacetic acid proceeds via the formation of an imine intermediate, followed by decarboxylation of the intermediate and hydrolysis to yield pyruvate. No evidence for an active reverse electron transport through a rotenone-insensitive path could be obtained. Except for vitamins A and K, regular intake of supplements had a significant positive influence on vitamin levels. Glutamate is likely responsible for severe brain damage in such cases [ 22 ]. The treatment also protected the blood-brain barrier and reduced the amount of lasting damage in the rat brain [ 22 ]. Major functions of this translocator are the export of reducing equivalents from the mitochondria via the malate-OA shuttle and the export of citrate via the citrate-OA shuttle. Since increased release of glutamate during epileptic seizures can lead to excitotoxicity and neuronal cell death, we tested the hypothesis that glutamate scavenging mediated by pyruvate and oxaloacetate systemic administration could have a neuroprotective effect in rats subjected to status epilepticus SE. A detailed knowledge of the interactions of the reactants with metal ions has been shown to be important in the calculation of the equilibrium constant and related thermodynamic functions. This little molecule plays an irreplaceable role in numerous cellular reactions and life-sustaining biochemical processes including: 2,3. The kinetic and chemical mechanism of amine-catalyzed decarboxylation of oxaloacetic acid at pH 8. Citrulline supplementation may be a better alternative than arginine, because its only fate in vivo is conversion into arginine.

While this response is critical for keeping us healthy, in some persons the response does not shut-off, such as in COVID patients with Long-Haul symptoms, and the energy of the cell is continually tied up in immune response [ 16 ]. Oxaloacetate is an important intermediate chemical in biosynthesis and is used as a health food based on its role in energy synthesis. Fatigue Scores were summarized as means and standard deviations, standard error and confidence intervals were calculated. The sporadic form of the disease affects the majority of amyotrophic lateral sclerosis ALS patients. The urea cycle is a metabolic pathway that results in the formation of urea using one ammonium molecule from degraded amino acids, another ammonium group from aspartate and one bicarbonate molecule. Dose escalation was used with new recruits to the study being placed in the current or next higher dosage group. Fumarase catalyzes the interconversion of fumarate and L-malate in the tricarboxylic acid cycle. Long-COVID patients that experienced at least 6 months of fatigue and did not have prior fatigue were recruited through social media. The transport specificities of some family members are known, but most are not. The three treatments tested induced a reduction in serum and brain glutamate levels, resulting in a reduction in infarct volume and sensorimotor deficit. The free energy of hydrolysis of acetyl-CoA has been evaluated from the present data.
