What Is Dehydrocholic Acid?
Dehydrocholic acid, also known as dehydicholic, is an organic compound. This odorless, white to slightly yellow solid is soluble in ethanol but almost insoluble in water.
Dehydrocholic acid is a semi-synthetic bile acid derived from the oxidation of cholic acid found in bovine bile. It serves as a cholecystokinin, aiding in digestion by increasing bile volume and components.
As an amphiphilic molecule, dehydrocholic acid not only functions as a medication but also as an emulsifier, enhancing the solubility of other drugs in water.
Uses of Dehydrocholic Acid
Dehydrocholic acid is utilized in medical treatments related to digestion and lipid absorption, notably in conditions like cholangiohepatitis and bile duct disorders, to enhance bile secretion. It also plays a role in lipid digestion by activating enzymes such as lipase.
While effective, its use can lead to side effects including diarrhea and abdominal discomfort, necessitating cautious application.
Additionally, its amphiphilic nature allows for its use as an emulsifier in drug formulations, making fat-soluble drugs easier to disperse in aqueous solutions.
Properties of Dehydrocholic Acid
Dehydrocholic acid, a secondary bile acid, aids in lipid absorption and digestion by activating certain enzymes. Its structure, featuring a hydrophilic carboxyl group and a hydrophobic carbon skeleton, allows it to emulsify lipids effectively.
This acid dissolves readily in organic solvents, highlighting its potential as an additive in pharmaceutical formulations.
Structure of Dehydrocholic Acid
Dehydrocholic acid’s steroid-based structure, adorned with carboxyl groups, grants it hydrophilic properties. This structural characteristic underpins its ability to emulsify lipids, blending water and oil components effectively.

How Dehydrocholic Acid Is Produced
Dehydrocholic acid production involves the oxidation of cholic acid, utilizing either chemical synthesis with oxidizing agents or biological methods via specific microorganisms.
1. Chemical Synthesis
This method uses oxidizing agents like hydrogen peroxide to convert cholic acid into dehydrocholic acid.
2. Biological Production
Microorganisms capable of transforming cholic acid into dehydrocholic acid are cultured, with the resulting acid extracted and purified from the culture medium.
Ensuring the purity of dehydrocholic acid requires effective separation and purification techniques, such as chromatography.
