REVIEW Lithocholic acid is a steroidal bile acid that acts as a detergent to solubilize fats for absorption. It is produced by bacterial metabolism in the colon from chenodeoxycholic acid. It has been implicated in human and experimental animal carcinogenesis, with preliminary in vitro work indicating that it selectively kills neuroblastoma cells, while sparing normal neuronal cells and is cytotoxic to numerous other malignant cell types at physiologically relevant concentrations. Lithocholic acid and its acetate and propionate esters can activate the vitamin D receptor without raising calcium levels as much as vitamin D itself.
