Webb6 sep. 2024 · 4 DISCUSSION. Lactate was once thought to be associated with fatigue during exercise, but is now seen as an important energy substrate. It not only serves as the link between glycolytic and oxidative metabolism within a cell but is also shuttled between cells and tissues (Brooks, 2024).Although the lactate shuttle theory (Brooks, 1986) is … Webb21 feb. 2024 · The Lactate Shuttle theory is applicable to diverse fields such as sports nutrition and hydration, resuscitation from acidosis and Dengue, treatment of traumatic brain injury, maintenance of glycemia, reduction of inflammation, cardiac support in heart failure and following a myocardial infarction, ...
The lactate shuttle hypothesis describes the movement of lactate intracellularly (within a cell) and intercellularly (between cells). The hypothesis is based on the observation that lactate is formed and utilized continuously in diverse cells under both anaerobic and aerobic conditions. Further, lactate produced … Visa mer Prior to the formation of the lactate shuttle hypothesis, lactate had long been considered a byproduct resulting from glucose breakdown through glycolysis in times of anaerobic metabolism. As a means of … Visa mer Redox signaling As illustrated by the peroxisomal intracellular lactate shuttle described above, the interconversion of lactate and pyruvate between cellular compartments plays a key role in the oxidative state of the cell. Specifically, … Visa mer Highly malignant tumors rely heavily on anaerobic glycolysis (metabolism of glucose to lactic acid even under ample tissue oxygen; Warburg effect) and thus need to efflux lactic … Visa mer In addition to Cori Cycle, the lactate shuttle hypothesis proposes complementary functions of lactate in multiple tissues. Contrary to the long-held belief that lactate is … Visa mer The lactate shuttle hypothesis also explains the balance of lactate production in the cytosol, via glycolysis or glycogenolysis, and lactate oxidation in the mitochondria … Visa mer As found by Brooks, et al., while lactate is disposed of mainly through oxidation and only a minor fraction supports gluconeogenesis, … Visa mer WebbLaktat-Leistungsdiagnostik Am 2.
