1. Introduction Bile acids are amphiphilic molecules that are produced primarily by the liver and secreted into the intestine to aid in fat emulsification and absorption. However, not only are bile acids present in the gut but they can also be found in serum. There is increasing evidence that bile acids perform many more functions in the body than simply supporting fat emulsification in the intestine [1]. Bile acids are involved in and influence many metabolic processes and disease states [2].
