Medchemexpress LLC 7-keto-Deoxycholic acid | 911-40-0 | 99.7% | 406.56 | 50 MG
7-keto-Deoxycholic acid is a metabolite of bile acids found in *Clostridium absonum*. It can also be converted from *Lactobacillus* and *Bifidobacterium* under specific conditions. It shows an increasing bioconversion rate with the addition of an equimolar concentration of deoxycholic acid and is induced by deoxycholic acid and then metabolized. *E. lentum*-like c-25 converts 81.7% of 2 mM cholic acid to deoxycholic acid and 3.7% to 7-keto-Deoxycholic acid under anaerobic incubation. *E. lentum*-like c-25 also converts 91.5% of 150 mg/mL cholic acid to deoxycholic acid and 1.1% to 7-keto-Deoxycholic acid under anaerobic incubation.
