General description

Taurocholic acid sodium salt hydrate is a bile acid with detergent capabilities.


Taurocholic acid sodium salt hydrate has been used in a study to assess the adsorption of bile acids and salts to vegetable fibrous tissue. It has also been used in a study to investigate a method for determination of conjugated and unconjugated bile salts in serum and jejunal fluid.
Anionic detergent used for protein solubilization.

Bile Acids

The liver excretes excess cholesterol in the form of bile acids. Bile acids serve two purposes: to remove unwanted cholesterol from the body and to aid in lipid digestion in the intestine.

Probiotics and Human Health

Today, diverse studies report the benefits of probiotics, such as inhibitory effects on pathogens, aid in the management or prevention of chronic intestinal inflammatory diseases or atopic syndromes, and support to the immune system. Potential beneficial applications abound, researchers continue to evaluate the effictiveness and clarify the mechanisms of action of probiotics.


Fast and Robust HPLC Separation of Bile Acids and Conjugates with Ascentis Express C18

This method is particularly useful in research into the role of individual bile acids as signaling molecules; suitable for clinical laboratories to investigate potential mechanisms linked to gut hormone profiles and glycemic control.
