Answer: micelles
Fat is a common example of lipids. Lipid is a fat like molecule that cannot dissolve in water, as a result fats are accumulated in clusters hence there is a difficulty in fat digestion.As it clumps together. It moves as droplets through the digestive system .By the time fat reaches the small intestine it has not been digested at all so the dietary fat in the small intestine looks like a fairly large globs of fat. These globs remain until the bile that is produced in the liver and stored in the gall bladder mixes with the large fat droplets.
Bile contains bile salts which acts as an emulsifier (breakdown of large fat droplets into smaller droplets) of lipids.
So the bile salts breakup and coat the fat in the small intestine to form much finer droplets these finer droplets have more surface area and this aids digestion because the fat digesting enzyme pancreatic lipase can only act on the surface of fat droplets. when the pancreatic lipase act on the lipid it breaks it down which results in free fatty acids and monoglycerides which are the two digestive products of lipids.
The absorption occurs within the epithelium cells and their transportation is done by fatty acids, and triglyceride.
