L-Lactic Acid
L-lactic acid is a chemical substance with the molecular formula of C3H6O3. It is an optical isomer of lactic acid. It is an organic acid refined by biological fermentation using corn starch as raw material. It is a colorless clear viscous liquid. The aqueous solution shows acidic reaction. It can be freely mixed with water, ethanol or ether, and is insoluble in chloroform. Because of its left-handed characteristics, it has good biological compatibility, can be compatible with mammals, can directly participate in human metabolism, without any side effects, and is widely used in food, medicine and other fields.
Difference Between L-Lactic Acid & D-Lactic Acid
Lactic acid is the smallest chiral molecule in nature, and the carboxyl group in the molecule α The position carbon atom is an asymmetric carbon atom with L (+) and D (-) configurations. L-lactic acid is left-handed type, D-lactic acid is right-handed type, L-lactic acid and D-lactic acid are mixed in equal proportion to form racemic DL-type. The physical and chemical properties of D-lactic acid and L-lactic acid are the same except for their optical activity, but the physical properties of DL-type are different from them, which is shown in that their melting point and heat of melting are lower than those of single D or L configuration.
D-lactic acid is dextral lactic acid, which cannot be absorbed by human body; L-lactic acid is L-lactic acid that can be absorbed by human body; DL-lactic acid is mixed rotational lactic acid. D-lactic acid and L-lactic acid are optical isomers of each other. DL-lactic acid is their mixture.

FAQs of L-Lactic Acid
What is L-lactic acid used for?
L-lactic acid is used for food, as an acid and preservative, as well as medical raw materials, disinfection and sterilization; Industrial grade is used for pesticide, feed and cigarette to keep moisture and remove odor; It can also be used for alcohol and condiments, adjust PH value and promote fermentation; Etc.
FAQ
Is L-lactic acid the same as lactic acid?
Lactic acid contains L-lactic acid; D-lactic acid; DL-lactic acid,
L-lactic acid is left-handed type, D-lactic acid is right-handed type, L-lactic acid and D-lactic acid are mixed in equal proportion to form racemic DL-type. Therefore, lactic acid contains L-lactic acid, while L-lactic acid is not equal to lactic acid.
FAQ
Is L lactic acid safe?
Security. L-lactic acid is L-lactic acid, which can be absorbed by human body and can be used in food additives.
