lactic acid

One of the byproducts of sugar metabolism in the body, with the chemical formula C₃H₆O₃, is produced due to insufficient oxygen supply in the body. This colorless compound is generated by all body tissues.

Lactic acid bacteria are used in the food industry to produce fermented products such as yogurt, cheese, sausages, and kefir. In fact, the final product of lactic acid bacteria is lactic acid, which is naturally present in the environment and even in the human digestive system.
