What is lactic acid.
Lactic acid is an intermediate product of sugar metabolism.
Generally speaking, the human body needs aerobic metabolism. Glucose can be converted into pyruvate, which generates energy through the tricarboxylic acid cycle, and pyruvate generates lactic acid. A small amount of lactic acid is produced during aerobic metabolism.
Under high pressure and low oxygen conditions, the mitochondrial tricarboxylic acid cycle and oxidative phosphorylation pathways are saturated or metabolically disturbed. The glycolysis pathway produces energy and lactic acid, and the production of lactic acid increases. Lactic acid is converted to cycloacetone through the tricarboxylic acid cycle, thereby reducing the level of lactic acid.
Method of producing lactic acid.
Generally speaking, 15-20 millimoles/lactic acid is produced every day, mainly from skin, red blood cells, brain and skeletal muscle. Most of the lactic acid is metabolized in the liver, and a small amount is produced in the kidney.
And lactic acidosis and even lactic acidosis can cause lactic acidosis. Lactic acidosis is divided into organized (A) and unorganized (B). Systemic or local histamine deficiency (e.g., adrenaline, arterial embolism), decreased blood supply or decreased tissue oxygen supply (e.g., severe hypoxemia, severe adrenaline poisoning), increased glycolysis (strength exercise) Wait. Generally speaking, type B lactic acidosis has no obvious organization. It may be that beta receptor agonists cause increased glycolysis and pyruvate dehydrogenase complex poisoning (for example, lack of thiamine or other toxins or drugs). There are also Coenzyme I/Oxidized Coenzyme I (for example, alcoholism), and lactic acid clearance disorders (for example, liver failure).
