Normal lactate production and metabolism  Lactate, the anion that results from dissociation of lactic acid, is a product of glucose metabolism; specifically it is the end product of anaerobic glycolysis.
Lactate can also be sent to the brain and heart for fuel, or to the liver to be converted to glucose, or move to active and inactive muscles and used as energy. We know the value of lactic acid today, but it is still misunderstood, and in the past, it was even viewed as a muscle poison.
Lactic acid is formed from glucose and used by working muscles for energy. Now it is thought that muscle cells convert glucose or glycogen to lactic acid. The lactic acid is absorbed converted to a fuel by mitochondria in muscle cells.
Lactate (Lactic Acid) is a byproduct of anaerobic metabolism. Normally, the tissues use aerobic metabolism to breakdown glucose for energy and the byproduct is CO2 and H2O which we excrete through our kidneys and exhalation. However, if the tissues are starved of oxygen (hypoxic), they use anaerobic metabolism.
Lactic acid is not evil and your muscles are not anaerobic. He and other colleagues have also shown that the lactate part of lactic acid can actually be a fuel for muscles and the heart and that the acid part of lactic acid is not the cause of fatigue. It might be a contributor, but fatigue is multi-dimensional and caused by a number of factors.
The Lactic Acid Myth. One of the end products of the break down of glucose is pyruvate, and this molecule begins to build up in our cells along with the hydrogen ions. Since our body doesn’t want these concentrations to rise unchecked, each molecule of pyruvate absorbs …
(Lactate is the name of the form of lactic acid that has donated a proton, as all acids by definition do. This « -ate » and « -ic acid » naming convention for acids spans all of chemistry.) This « -ate » and « -ic acid » naming convention for acids spans all of chemistry.)

It is a useful marker used by doctors to establish hyperlactatemia. This may be due to severe sepsis , septic shock , or as a reaction to drugs, such as some antiretrovirals.
Lactate and exercise . Lactate has often been considered one of the major causes of both fatigue during exercise and post-exercise muscle soreness. However, lactate may have little effect on either. Moreover, it may help to improve performance. Accumulation of lactic acid (generated form the anaerobic breakdown of glycogen), in the muscle
Lactic acid does not equal lactate! It is lactate accumulation in the muscles and bloodstream, not lactic acid. Even in the presence of adequate oxygen, which is a common misconception.
