Metabolite Identification
Common Name12-Ketodeoxycholic acid
Description12-Ketodeoxycholic acid is a bile acid derivative belonging to the class of steroid compounds. Chemically, it is characterized by a ketone group at the 12th carbon position of the deoxycholic acid structure, which influences its solubility and biological activity. This metabolite is involved in various biochemical pathways, including the regulation of bile acid metabolism and modulation of gut microbiota. Notably, plasma metabolomic analyses have identified 12-ketodeoxycholic acid as a differentially accumulated metabolite, positively correlating with Clostridium and Romboutsia, which suggests its role in gut health (PMID:40947000 ). Additionally, 12-ketodeoxycholic acid is enriched in dysregulated bile acid profiles associated with high-fat diets, contributing to the production of secondary bile acids that exert anti-inflammatory effects (PMID:39308187 ). Its levels have also been linked to metabolic conditions such as non-alcoholic fatty liver disease (NAFLD) and cirrhosis, where it serves as a potential biomarker for differentiating between disease states (PMID:31956867 , PMID:35409192 ). Overall, 12-ketodeoxycholic acid plays a significant role in the complex interplay between diet, gut microbiota, and metabolic health.
