Bile acids are a group of molecules primarily produced in the liver and secreted into the digestive tract to aid in the digestion and absorption of fats. They play a critical role in the emulsification and absorption of dietary lipids, as well as in the regulation of cholesterol metabolism. Research in the field of bile acids includes studying their role in various physiological processes such as lipid metabolism, energy homeostasis, and gut microbiome modulation. Additionally, researchers are investigating the potential therapeutic applications of bile acids in the treatment of metabolic disorders, liver diseases, and gastrointestinal conditions. Overall, the study of bile acids is a rapidly expanding field with implications for both basic science and clinical medicine.
