Q.5: How are fats digested in our body? Where does this process takes place?
Digestion of Fat:
Digestion of fat takes place in the small intestine. The fats are present in the form of large globules in the small intestine. Fat-digesting enzymes are not able to act upon large globules efficiently.
Bile juice secreted by the liver is poured into the intestine along with pancreatic juice. The bile salts present in the bile juice emulsify the large globules of fats. So, due to emulsification large globules breakdown into small globules, which provide larger surface area to act upon by the enzymes.
Lipase enzyme present in the pancreatic juice causes breakdown of emulsified fats. Glands present in the wall of small intestine secrete intestinal juice which contains lipase enzyme that converts fats into fatty acids and glycerol.
