How does butter in your food get digested and absorbed in the body?

Butter is fat content and it is completely digested in the small intestine. The bile juice secreted by the liver contains bile salts that break down large fat globules into smaller globules, to increase their surface area for the action of lipase. This process of breakdown of fats is known as the emulsification of fats. After this, the pancreatic lipase present in the pancreatic juice and the intestinal lipase present in the intestinal juice hydrolyzes the fat molecules into triglycerides, diglycerides, monoglycerides, and ultimately into glycerol.

Absorption of fats: The process of absorption of fats is an active process where fats are hydrolyzed or converted into fatty acids and glycerol. However, since these are water-insoluble, they cannot be directly absorbed by the blood. So, at first, they are incorporated into small droplets called micelles and then transported towards the intestinal mucosa villi developed during the organism’s lifetime. They are then transformed into small microscopic particles called chylomicrons. These are small, protein-coated fat globules that are transported to the lymph vessels in the villi. The absorbed food is finally released into the bloodstream from the lymph vessels and from there to each cell of the body.
