Answer

  2. Bile contains salts, namely, sodium glycolate and sodium taurocholate. These reduce the surface tension of large fat droplets and break them into many small ones. The process is called emulsification. Bile salts also form a thin coating around tiny fat droplets to keep them free from each other.
