Medchemexpress LLC 7-keto-Deoxycholic acid | 911-40-0 | 99.71% | 406.56 | 25 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 exhibits an increased bioconversion rate when an equimolar concentration of deoxycholic acid is added.
- Induced by deoxycholic acid and subsequently metabolized
- *E. lentum-like c-25* converts cholic acid to deoxycholic acid and 7-keto-Deoxycholic acid under anaerobic incubation
