Question

Harsh took bread and butter for his breakfast. Explain the course of digestion of butter in his digestive system. Also mention the enzymes involved.

Answer 1

Butter is a fat product and gets digested in the small intestine. The bile juice secreted by the liver contains bile salts that break down large fat globules into smaller globules, so as to increase their surface area for the action of lipase. This process is referred to as emulsification of fats.

After this, the pancreatic lipase present in the pancreatic juice and the intestinal lipase present in the intestinal juice hydrolyse the fat molecules into triglycerides, diglycerides, monoglycerides, and ultimately into glycerol and fatty acids.

Answer 2

As the person takes bread and butter in breakfast he takes a diet which is rich in fats. Fats are digested in the body by first converting them into simple sugars in the mouth and then their actual digestion takes place through the secretion of bile juice from liver.
