C3H6O3, commonly known as lactic acid, is an organic compound with a colorless appearance and a slightly sour taste. It is produced naturally in the body during the process of anaerobic respiration, particularly in muscle cells when oxygen levels are low. Lactic acid plays a crucial role in energy production, especially during intense physical activity. In addition to its biological significance, lactic acid is widely used in the food industry as a preservative and flavoring agent. It is also found in various fermented products, such as yogurt and pickles. Furthermore, lactic acid is utilized in the cosmetic and pharmaceutical industries for its exfoliating properties.
