DL-lactic acid
Name: DL-lactic acid
CAS: 598-82-3
Feature:
Lactic Acid, DL- is the racemic isomer of lactic acid, the biologically active isoform in humans. Lactic acid or lactate is produced during fermentation from pyruvate by lactate dehydrogenase. This reaction, in addition to producing lactic acid, also produces nicotinamide adenine dinucleotide (NAD) that is then used in glycolysis to produce energy source adenosine triphosphate (ATP). Lactic acid is chiral, consisting of two enantiomers. One is known as l-lactic acid, (S)-lactic acid, or (+)-lactic acid, and the other, its mirror image, is d-lactic acid, (R)-lactic acid, or (−)-lactic acid.
DL-lactic acid is an organic acid. It has a molecular formula CH3CH(OH)COOH. It is white in the solid state and it is miscible with water. When in the dissolved state, it forms a colorless solution. Production includes both artificial synthesis as well as natural sources. DL-lactic acid is an alpha-hydroxy acid (AHA) due to the presence of a hydroxyl group adjacent to the carboxyl group. It is used as a synthetic intermediate in many organic synthesis industries and in various biochemical industries. The conjugate base of lactic acid is called lactate.
DL-lactic acid has the following applications/functions:
1. DL-lactic acid is employed in pharmaceutical technology to produce water-soluble lactates from otherwise-insoluble active ingredients. It finds further use in topical preparations and cosmetics to adjust acidity and for its disinfectant and keratolytic properties.
2. DL-lactic acid is used as a food preservative, curing agent, and flavoring agent. It is an ingredient in processed foods and is used as a decontaminant during meat processing. Because the acidity of DL-lactic acid is mild and stable, it contributes to the flavor of food, and is widely used as an acidulant, preservative and reducing agent in the food industry.
3. Lactic acid is used in some liquid cleaners as a descaling agent for removing hard water deposits such as calcium carbonate, forming the lactate, calcium lactate.
