Best answer


Lactateis a source of energyfor the muscles, heart and brain. Muscles can extract lactate from the blood and oxidise it directly, using it as a fuel source to liberate energy for contraction (Van Hall, 2000). In some cases, the body actually prefers to use lactateas a fuel.

  • Lactate and pyruvate together serve as a circulating redox buffer that equilibrates the NADH/NAD ratio across cells and tissues. This reconceptualization of lactate as a fuel-analogous to how Hans Christian Andersen’s ugly duckling is actually a beautiful swan-has the potential to reshape the field of energy metabolism.

  • What is lactic acid and why is it important?

  • Lactate can fuel the brain or the heart as a source of energy, or it can be converted to glucose in the liver. Gluconeogenesis is the formation of glucose in the liver and it is lactate that is the most important ingredient for this function. But the simple fact remains that there is a correlation between lactic acid in the body and fatigue.
