[RESOLVED] What Is The Site Of Fat Digestion In Humans?

Once the stomach contents have been emulsified, fat-breaking enzymes work on the triacylglycerols and diglycerides to sever fatty acids from their glycerol foundations 🙌 As pancreatic lipase enters the small intestine, it breaks down the fats into free fatty acids and monoglycerides 😁 Yet again, another hurdle presents itself. The fats will not be able to pass the layer of watery mucous which covers the absorptive liner of the stomach. Bile is the solution, just like before. To form micelles, bile salts surround the monoglycerides and fatty acids. Micelles contain a core of fatty acids with a water-soluble outer. It allows for efficient transport to the microvillus. The resulting slurry is called the fat components are released and disseminated into the cells of the digestive Tract Lining [1]
After the stomach contents are emulsified fat-breaking enzymes can be used work on the triacylglycerols and diglycerides to severe fatty acids from their glycerol foundations. When pancreaticlipase enters small intestine it begins to break down fats and create monoglycerides. Another hurdle is presented. What will happen to the fats when they are trapped in the mucus layer that covers the absorptive membrane of the stomach? Bile is the solution, just like before. To form micelles, bile salts surround the monoglycerides and fatty acids. Micelles contain a core of fatty acids with a water-soluble outer. It allows for efficient transport to the microvillus. The fats are then released into the intestinal microvillus and distributed to the cells in the intestinal lining. Akeem Espinosa, Matsuyama (Japan) last updated this 55-days ago [2]

Our friends at med.libretexts.org It is important to note that once stomach contents are emulsified fat-breaking enzymes work with the triglycerides or diglycerides in order to remove fatty acids form their glycerol bases. Pancreatic lipase is able to break down fats in the small intestine into monoglycerides and free fatty acids. Another hurdle is presented.

Researchers at openoregon.pressbooks.pubLipid digestion and absorption present some unique challenges. Triglycerides are large molecules, and unlike carbohydrates and proteins, they’re not water-soluble. Because of this, they like to cluster together in large droplets when they’re in a watery environment like the digestive tract. These are The digestive process has to break those large droplets of fat into smaller droplets and then enzymatically digest lipid molecules using enzymes Lipases are also known. Although the stomach and mouth play some role, most of the enzymatic digestion of lipids takes place in small intestine. There, you will find the final products. Lipid digestion are absorbed into circulation and transported around the bodyThis requires special handling as lipids cannot be water-soluble so they must not be mixed with watery blood.
