👉 The term "cholecyanine" is used to describe a substance that is produced in the liver and plays a crucial role in the digestion of fats. It is composed of two main components, choline and acetylcholine, which are essential for proper fat breakdown in the body. Cholecystokinin (CCK) also plays a role in regulating digestion, but it's not directly related to the production or function of cholecyanine.
