Is learning fat digestion giving you a hard time?
Here is Lipid digestion and absorption made easy. Remember to read the narrative at the right side of the gif.
- Fat digestion unlike carbohydrates and proteins, begins in the first part of the small intestine (duodenum).
2. The small intestines have finger like projections called villi and micro villi which increase the absorptive surface area of the small intestine.
3. Bile is a green substance produced by the Liver and is stored in the gall bladder. It is very important in the digestion and absorption of fats.
4. After the fatty food gets into the first part of the small intestine ( the duodenum), The walls of the gall bladder is squeezed to release bile.
5. The bile is released from the gall bladder and is transported to the duodenum ( where the food is) through the common bile duct. In addition to this, some enzymes from the pancreas are also released which are also needed for fat digestion. They are called LIPASES.
6. The pancreatic enzymes released from the pancreas get to the duodenum ( first part of the small Intestine) though the pancreatic duct. Bile salts help to break the fat goblets into smaller pieces.
7. Bile salts ( contained in bile) emulsify ( break down fat globules into smaller pieces) so that the Lipases from the pancreas can act on the fat/lipid.
9. Lipase from the pancreas breaks down the fat/lipid into fatty acids and monoglycerides. Fatty acids and monoglycerides can easily pass through the epithelial cells of the intestine where absorption takes place.
This is the story of the digestion of lipids. We would be posting about the absorption of lipids soon!
