Edit Comment Close Premium member Presentation Transcript Digestion of Lipids : Digestion of Lipids The major dietary lipids are TRIACYL GLRCEROL CHOLESTEROL PHOSPHOLIPIDS Digestion in Mouth : Digestion in Mouth Very little amount of lipid digestion takes place in mouth because of the presence of Lingual lipase. Lingual lipase action continues in stomach also. It acts mainly on short chain Tryglycerides. Digestion in stomach : Digestion in stomach Lipids are emulsified by peristaltic movements Gastric lipase is an important lipid digesting enzyme in stomach. Around 30% digestion of TAG occurs in stomach Digestion in Intestine : Digestion in Intestine Bile Bile Salts Pancreatic Juice – Pancreatic Lipase Co Lipase Cholesterol esterase Phospholipases. All these lipases target primary ester linkage. Emulsification Neutralization of acid Absorption of lipids : Absorption of lipids The end products of lipid digestion are Fatty acids Glycerol 2-Monoacylglycerol 1- Mono acylglycerol Cholesterol Lysophonpholipid Glycerol Small chain FA Medium chain FA, are directly absorbed from Intestinal lumen into portal vein and are taken to liver. : Glycerol Small chain FA Medium chain FA, are directly absorbed from Intestinal lumen into portal vein and are taken to liver. Slide 7: Other end products like Long chain FA, Cholesterol, Phospholipids, lysophospholipids and 2-mono acylglycerides, are incorporated into molecular aggregates to Mixed Micelle. Slide 8: Glycerol, short- & medium-chain FA pass through straight to capillaries Enterocytes reesterify lipids (long-chain FA, etc) back to TGs & PLs ? chylomicrons (packaged in Golgi) secreted into lymphatics Re esterfication inside the Mucosal cell : Re esterfication inside the Mucosal cell Free fatty acids combine with mono acylglycerols to form TAG Cholesterol re esterifies to form cholesterol ester Iysophospholipid to phospholipid All these compounds along with apo-A and apo B 48 are incorporated into chylomicrons. These chylomicrons they enter into lacteals or lymph vessels. Abnormalities of Digestion & Absorption of Lipids : Abnormalities of Digestion & Absorption of Lipids STEATORRHEA Excretion of fat in faces more than 6 gms/day This is due to defective Digestion & absorption Usually seen in Chronic Pancreatitis Bile duct obstruction Coeliac diseases, sprue, crohn’s diseases Chyluria Chylothorax GI Problems : Irritable Bowl Syndrome Visible abdominal distension Crohn’s disease No cure Eliminate specific foods GI Problems Constipation : Constipation Slows movement of fecal matter Increases fluid reabsorption; hardening of the feces Causes: Results from ignoring normal urge Antacids, calcium and iron supplements Treatment Plenty of dietary fiber and fluids Laxatives Heartburn : Heartburn Gastroesophageal reflux disease Gnawing pain in the upper chest Acid from the stomach to the esophagus Treatment Smaller meals Less fatty meals Stop smoking Do not lie down after eating Avoid offending foods Ulcers : Ulcers Helicobacter pylori Heavy use of aspirin Excessive acid production in the stomach Symptoms Pain 2 hours after eating Treatment Antibiotics Antacid You do not have the permission to view this presentation.
