Digestion Of Fats

How Fat is Digested

no real breakdown of fat occurs until the fats reach the duodenum in the form of gastric chyme.

Fat breakdown in the small intestine

Fat digestion and absorption requires that the complex fat molecules be broken down into smaller molecules. It's done by the Lipase and the it chops up lipid molecules into fatty acid molecules and glycerol molecules. And mixing the fat with the digestive enzyme lipase, which enters the duodenum from the pancreas. Also fat does not dissolve in water, the fat molecules enter the duodenum in a large mass, which makes it hard for the pancreatic lipase enzymes to attack them, since lipase is a water soluble enzyme can only attack the surface of the fat molecules. And Emulsification allows lipase to gain easier access to the fat molecules and this accelerates their breakdown and digestion.

How Fat Is Digested And Absorbed Into The Bloodstream

Lipase and other digestive juices break down the fat molecules into fatty acids and types of glycerol. Absorption of fat into the body, that will take about 10-15 minutes, will occur in the villi. And only about 5% of absorbed fat can be converted into glucose, a significant proportion of digested fat is typically stored as body fat in the adipose cells. The glycerol part is absorbed by the liver and is either converted into glucose, and used to help breakdown glucose into energy.


Digestion and Absorption of Food Fats

Cholesterol is the precursor to bile acids, which are needed to digest and absorb fatty acids. Saturated fatty acids in membrane integrity by having appropriate fatty acids for certain parts of membrane structures. Polyunsaturated fatty acids also provide raw material for membranes, and work as precursors to the various prostaglandins. Fat digestion of phospholipids and other lipids makes up very small, but important, part of the building blocks for tissue.Usually The digestion of regular fats and oils, requires bile acids as well as lipases. 95 % of the fat is available for digestion when the mixture of fatty acids is varied.Short- and medium-fat acids such as milk fat or coconut oil or palm kernel oil are broken off from the triglycerides without the need for bile. Fat digestion of cholesterol and other sterols is not described correctly. Cholesterol and other sterols do not have any calories, and the amount that is absorbed is small except in infants. The slow digestion of fat is really nature’s way of keeping an even amount of the energy.
