L-lactic acid is a chemical substance with the molecular formula C3H6O3. It is an optical isomer of lactic acid. It is an organic acid made from corn starch through biological fermentation and refinement. It is a colorless, clear, viscous liquid, and its aqueous solution shows an acidic reaction. It can be mixed with water, ethanol or ether at will, and is insoluble in chloroform. Due to its left-handed characteristics, it has good biocompatibility, can be integrated with mammals, can directly participate in human metabolism, has no side effects, and is widely used in food, medicine and other fields.
