to emulsify and also digest fats

Detailed explanation-1: -When digesting fats, bile acts as an emulsifier to break the large fat globules into smaller emulsion droplets. Emulsified fats provide a larger area for the fat-digesting enzymes (lipase) to act, making the process quicker. Bile acts as a good solvent.
Detailed explanation-2: -One of bile’s jobs is to emulsify fats, meaning it enables fat and water to mix. Bile contains molecules that are partly attracted to fat and partly attracted to water. These molecules draw fat and water together by sandwiching themselves in between the two.
Detailed explanation-3: -Bile juice emulsifies fats and breaks them down into small particles. This is a detergent-like action of bile that helps the body to absorb the broken-down fat products in the gut.
Detailed explanation-4: -Emulsification: In the small intestine lipids are emulsified by bile salts. Bile salts (bile salts = conjugation of bile acids with taurine or glycine) are polar and water soluble and function as detergents whereby they emulsifies larger fats into smaller droplets.
