What is sodium deoxycholate used for? Sodium deoxycholate is a bile acid salt. It contains a deoxycholate. A bile acid formed by bacterial action from cholate. It is usually conjugated with glycine or taurine. Deoxycholic acid acts as a detergent to solubilize fats for intestinal absorption, is reabsorbed itself, and is used as a choleretic and detergent.
