담즙질, or "bile acid," is a substance produced by the liver and stored in the gallbladder. It plays a crucial role in the digestion of fats by emulsifying them, which helps the body absorb fat-soluble vitamins like vitamin A, D, E, and K. When we eat, bile is released into the small intestine to aid in the breakdown of dietary fats. This process is essential for proper digestion and nutrient absorption, ensuring that the body receives the energy and nutrients it needs from food.
