Ursodiol is which of the following?

• A. A carbohydrate
• B. A mineral
• C. A protein
• D. Ursodeoxycholic acid, a bile acid that may improve fat absorption

Answer: (D)

Ursodiol is ursodeoxycholic acid, a bile acid. It is not a carbohydrate, mineral, or protein. Bile acids are detergents produced by the liver that emulsify fats, helping form micelles so fats and fat-soluble vitamins (A, D, E, K) can be absorbed in the small intestine. Ursodeoxycholic acid is used therapeutically to improve bile flow in certain liver conditions and can aid fat absorption by enhancing bile’s ability to emulsify fats.
