Life Processes


How are fats digested in our bodies? Where does this process take place?


The food which enters into the small intestine contains large molecules of fats. The small intestine receives the secretion from the liver and pancreas. The liver secretes bile juice which makes the food alkaline for trypsin to act and help in the emulsification of fat.  Bile juice secreted from the liver breakdown the large molecules of fats into small globules. This is called the emulsification of fat.

The pancreas secretes pancreatic juice which contains trypsin and lipase enzyme. Lipase enzyme helps in the breakdown of emulsified fats and converts fats into fatty acids and glycerol.
