in this ppt you will know alot about the mechanism by which the fats are digested into fatty acids and how it be absorped to enter the circulation

1. Digestion and absorbation of lipids

2. Major lipids:triacylglycerol-
cholestrol-free fatty acid-
phospholipids .
Libids are insoluable in Aqueous S.
Digestive enzymes present in
Aqueous S .

3. We can overcome this problem through:
Increase surface area of digestion of
lipids .
Solubiliz The digested Product for
absorbation .
Emulsification of lipids by bile salts .

4. Digestion in stomach:
 The heat of the stomach liquidizes the
lipids .
 Emulslification started by Peristaltic
concentration .
 Both lingual and gastric lipase acts on SCTs.
 SCTs exist in milk and rettub
.
 So, Action of enzymes are good in newborns

5. Digestion in small intestine:
 Ssmulsification is essential for lipid
digestion and done by bile salts and
peristalsis.
 It make lipids small droplets by reducing
surface tension.
 Bile salts are biological detergent helps in
emulsification of lipids forming micelle
 Formed by cholesterol in liver and secreted
with bile in small intestine

6. Digestion by pacreatic enzymes
1. Pancreatic lipase for TGL

7. Digestion of phospholipids:
 Phospholipase-A 2

2 position of glycerophospholipid,
producing lysophospholipid that being
detergent, helps in emulsification and
digestion of lipids .

8. Digestion of cholesterol ester:
Produce cholesterol and free fatty
acid.

9. Absorbation:

10. Absorbation In intestine:

11. Absorbation in intestine:

12. Abnormalities of lipid digestion and
absorbation:
1. Lipids malabsorbatn
2. Steatorrhea :loss lipid in feces
Duo to salts deficiency and
pancreatic enzymes deficiency
