Bile is not actually acidic; it is alkaline or basic in nature. The acidity or alkalinity of a substance is determined by its pH level, ranging from 0 to 14. A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline.
Bile is produced by the liver and stored in the gallbladder. Its primary function is to aid in the digestion and absorption of fats in the small intestine. When fatty foods reach the stomach, it triggers the release of a hormone called cholecystokinin (CCK) from the small intestine. CCK signals the gallbladder to contract, releasing bile into the duodenum (first part of the small intestine).
Although bile is alkaline, it helps with the digestion of fatty acids by emulsifying them. Emulsification is the process of breaking down large fat globules into smaller droplets, increasing their surface area and allowing digestive enzymes called lipases to work more effectively.
So, to recap, bile itself is alkaline and helps neutralize the acidic environment of the stomach when it enters the duodenum. This alkaline nature of bile aids in the digestion and absorption of fats in the small intestine.
