Applications of Cholic Acid

Applications of Cholic Acid


Cholic Acid is a natural product, produced from cholesterol in the liver of many animals, including humans. Typically, the liver converts cholesterol into the conjugated forms of cholic acid, glycocholic and taurocholic acid. These are then released into the small intestine where it was originally thought they served primarily to emulsify fats and promote digestion. However, recent research has shown the impact of bile acids on many different signalling pathways both inside and outside the gastro-intestinal system, leading to a resurgence of interest in bile acids as therapeutic molecules. NZP is at the forefront of many of these efforts, supplying cholic acid and various other bile acid derivatives to the pharmaceutical and biotechnology sector.

The primary industrial use of Cholic Acid is as an intermediate for the production of ursodeoxycholic acid (UDCA, Ursodiol), an active pharmaceutical ingredient which is used to treat several indications including Primary Biliary Cholangitis (also known as Primary Biliary Cirrhosis or PBC), the dissolution of gall stones and the liver damage caused by Hepatitis C infection.

Cholic Acid itself is also used as an active pharmaceutical ingredient for the treatment of bile acid synthesis disorders and is approved for use in both the US and Europe.

In addition, Cholic Acid also sees use in Traditional and Modern Chinese medicines, as an intermediate in the synthesis of various other pharmaceutical products and as an ingredient in culture and bio-relevant media.
