What is Bile salts

Bile salts have a considerable ability to lower surface tension. By  this property, they prevent  the coming together of the small fat droplets in  the  intestine and thus allow more rapid digestion of the fat. This is called the emulsiJication  action of  bile.  Bile salts also  combine with  fatty acids  and  render  them more  easily absorbed.  This  is  called  hydrotropic  action  of  bile. The  presence of  bile  in  the intestine  is  to  accomplish digestion and absorption of fat and  also  of fat-soluble vitamins
