Answer:
Explanation:
1. Fatty acids and solid fats melt during mastication, and lingual lipase begins digestion.
2. Fats are broken up into smaller droplets in the stomach, and chief cells release gastric lipase.
3. As chyme enters the duodenum of the small intestine, cholecystokinin stimulates the gallbladder to contract and secrete bile, stimulating the secretion of digestive enzymes from the pancreas. (Lipase and amylase)
4. Bile from the gallbladder emulsifies Fat to form micelles in the duodenum.
5. Pancreatic lipase hydrolyzes tiglycerides and other lipids into micelles, and micelles transport monoglycerol, glycerol products and fatty acids.
6. Components of micelles create chylomicrons that enter the lymph.
The events from taking a bite of food rich in lipids to triglycerides being released to cells are ranked as - 3, 1, 4, 5, 2
Lipid digestion
The most common lipids found in foods are in the form of triglycerides. These lipids are hydrolyzed during digestion to yield mono acyl glycerides, glycerol, and free fatty acids. The process of digestion is
- You take a bite of food rich in lipids.
- Fats are broken up into small droplets in the stomach and chef cells release gastric lipase which hydrolyses some triglycerides. Solid fats melt during mastication and lingual lipase begins the digestion of triglycerides.
- As the chyme enters the duodenum of the small intestine, cholecystokinin stimulates the gall bladder to contract and release bile and stimulated the secretion of digestive enzymes from the pancreas.
- Bile from the gall bladder emulsifies large fat globules into smaller ones in the small intestine.
- Pancreatic lipase hydrolyses triglycerides into monoglycerides, glycerol, and fatty acid.
- Fatty acids and monoglycerides form micelles and micelles transport products of digestion to enterocytes that reform to form chylomicrons that enter the lymph. Short-chain fatty acids enter blood directly.
