Bile juice contains no digestive enzymes, yet it is important for digestion. Why?

Bile is a yellowish green alkaline solution with 89-98 % water, having no digestive enzymes.
The bile released into the duodenum contains bile pigments (bilirubin and biliver din), bile salts, cholesterol and phospholipids, but no enzymes. Bile helps in emulsification of fats, i.e., breaking down of the fats into very small micelles. Bile also activates lipases.
