emulsifying

Explanation:

Bile salts secreted from the bill has an important role in emulsification of lipids. They have the ability to aggregate around lipids thanks to their amphipatic nature. Amphipatic nature means that they have hydrophobic side which binds directly to lipids and hydrophilic side which are faced outwards. Lipids enveloped with bile salts are called micelles.

Formation of micelles increases the surface area of fat, which is appropriate for the the action of the enzyme pancreatic lipase (perform digestion of triglycerides).
