Aberrant pyruvate metabolism plays an especially prominent role in cancer, heart failure, and neurodegeneration. Because most major diseases involve aberrant metabolism, understanding and exploiting pyruvate carbon flux may yield novel treatments that enhance human health.

2019年5月30日 · When transported into the mitochondrion, pyruvate encounters two principal metabolizing enzymes: pyruvate carboxylase (a gluconeogenic enzyme) and pyruvate dehydrogenase (PDH). With a high cell-energy charge, acetyl-CoA, is able allosterically to activate pyruvate carboxylase, directing pyruvate toward gluconeogenesis.

Pyruvate, the end product of glycolysis, plays a major role in cell metabolism. Produced in the cytosol, it is oxidized in the mitochondria where it fuels the citric acid cycle and boosts oxidative phosphorylation.

2020年6月18日 · Pyruvate, the end product of glycolysis, plays a major role in cell metabolism. Produced in the cytosol, it is oxidized in the mitochondria where it fuels the citric acid cycle and boosts oxidative phosphorylation.

4 天之前 · Highlighting its critical role in pyruvate metabolism, MPC has been shown to be key in managing ATP production, regulating gluconeogenesis and shaping amino acids and lipids synthesis 5,6,8.

2013年12月21日 · Mitochondrial pyruvate metabolism is regulated by many enzymes, including the recently discovered mitochondria pyruvate carrier, pyruvate dehydrogenase, and pyruvate carboxylase, to modulate overall pyruvate carbon flux.

2020年4月4日 · His physician explains that a training regimen can increase his ability to perform aerobic metabolism, and thus decrease the conversion of pyruvate to lactate (via lactate dehydrogenase) which caused the burning in his muscles that he experienced.

2021年3月30日 · Pyruvate occupies a central metabolic node by virtue of its position at the crossroads of glycolysis and the tricarboxylic acid (TCA) cycle and its production and fate being governed by numerous cell-intrinsic and extrinsic factors.

Aberrant pyruvate metabolism plays an especially prominent role in cancer, heart failure, and neurodegeneration. Because most major diseases involve aberrant metabolism, understanding and exploiting pyruvate carbon flux may yield novel treatments that enhance human health.

The metabolism of pyruvate begins with its biosynthesis which can happen through 5 different sets of reactions. A) Lactaldehyde reacts with an NADPH dependent methylglyoxal reductase results in the release of a pyruvaldehyde.

Pyruvate, the end product of glycolysis, is an essential substrate for mitochondrial oxidative metabolism. Initially, pyruvate is transported through the outer mitochondrial membrane into the inter-membrane space by a voltage-dependent anion channel (VDAC). From there, the MPC facilitates its transport across the IMM into the mitochondrial matrix.

2013年11月12日 · Pyruvate is an obligatory intermediate in the oxidative disposal of glucose and a major precursor for the synthesis of glucose, glycerol, fatty acids, and non-essential amino acids. Stringent control of the fate of pyruvate is critically important for cellular homeostasis.

2024年10月17日 · Pyruvate is a pivotal molecule in cellular metabolism and energy production, acting as an intermediary that bridges various metabolic pathways. Its role extends beyond being just an end product of glycolysis; pyruvate serves as a substrate for further biochemical processes essential for life.

2024年12月14日 · Pyruvate serves as a crucial intermediate in cellular metabolism. In aerobic conditions, it is transported to the mitochondria and converted into acetyl-CoA, which enters the Krebs cycle for further ATP production.

2019年4月8日 · Pyruvate is generated by two primary methods – through the glycolytic pathway, and through the metabolism of amino acids. While proteins supply nearly 10% of the body’s energy needs, only some amino acids are channeled …

2020年7月17日 · Pyruvate, the end product of glycolysis, plays a major role in cell metabolism. Produced in the cytosol, it is oxidized in the mitochondria where it fuels the citric acid cycle and boosts oxidative phosphorylation.

2024年5月12日 · Metabolism of Pyruvate. The presence or absence of oxygen determines the fates of the pyruvate produced in glycolysis. When plenty of oxygen is available (aerobic conditions), pyruvate is first converted to acetyl-CoA. However, in the absence of oxygen (that is, under anaerobic conditions), the fate of pyruvate is different in different organisms.

2019年1月17日 · Pyruvate sits at an intersection of key pathways of energy metabolism. It is the end product of glycolysis and the starting point for gluconeogenesis and can be generated by the transamination of alanine.
