Lec 8-7 - Fat Digestion/absorption Flashcards
Emulsification by bile acids works best at this pH so blank from liver and pancreas fluid is important
6- 8.5, bicarbonate
Emulsification increases blank for the next step in the lumen
Surface area
Next step of fat digestion after emulsification
Breakdown by lipase
Step three of fat digestion after lipase action
Fat digestion products incorporated in to micelles
Concentration at which micelles form
Critical micelle concentration
For proper fat digestion we should have a blank critical micelle concentration
High
Micelles form in the lumen of blank and blank
Small intestine, gallbladder
High concentration of micelles means blank diffusion of fats through the unstirred layer
Rapid
4th step of fat digestion
Micelles diffuse through unstirred layer
Fat soluble vitamins
A,d,e,k
Fat soluble vitamins are absorbed via blank pathway
Micelle-chylomicron pathway
Fat soluble vitamins are not digested by blank
Lipase
Absorption of bile acids occurs here
Ileum
Bile acids are left after absorption of blank and blank from fat digestion
Cholesterol, lecithin
Most fats are long chained and are absorbed by blank pathway
Micelle chylomicron
