Lactic acid (chemical formula: C₃H₆O₃) is a naturally occurring organic carboxylic acid that serves as a crucial metabolic byproduct, ubiquitously present in fermented foods (e.g., yogurt, kimchi), animal muscle tissues, and microbial fermentation systems. Functioning both as a prototypical alpha-hydroxy acid (AHA) and a versatile industrial raw material, it is characterized by mild acidity, remarkable water solubility, and distinct antimicrobial properties. Existing in three stereoisomeric forms - L-lactic acid, D-lactic acid, and DL-racemic mixture - the L-isomer dominates industrial applications due to its superior biodegradability and biocompatibility, particularly in food and pharmaceutical sectors.
