Overview: there are two isomers of L-lactic acid and D-lactic acid (more than 90% of which are L-lactic acid). The clinical determination is mainly L-lactic acid, which is a sensitive index of tissue hypoxia. D-lactic acid is different from L-lactic acid. It has unique characteristics in source, metabolism, excretion and clinical significance. In recent years, the research and understanding of the above uniqueness of D-lactic acid have been deepened and improved. Under normal circumstances, D-lactic acid in the human body comes from the metabolism of acetone aldehyde, and the content in the blood is very small. When a large number of gastrointestinal bacteria are hydrolyzed and the function of the intestinal barrier is impaired, the content can rise a thousand times, and even lead to D-lactic acid poisoning.
