General description

Cholic acid is a major primary bile acid produced in the liver which facilitates fat absorption and cholesterol excretion. It is a non-denaturing ionic detergent.


Dietary cholic acid has been used in a study to assess its effect on colonic epithelial cell proliferation. It has also been used in a study to investigate extractions and comparisons of human erythrocyte ghosts.

Non-denaturing ionic detergent used for extraction of membrane proteins.
