Basic unit of fats and oils
Glycerol
Glycerol + 1 FA
Monoglyceride
Glycerol + 2 FA
Diglyceride
Glycerol + 3 FA
Triglyceride
During digestion the presence of fat in the _ stimulates the secretion of _
duodenum, cholecystokinin
_ regulates secretions of pancreas enzymes and bile
cholecystokinin
_ _ emulsify the fat droplets, and create smaller droplets with larger _ _
Bile salts, surface area
- binds the fat droplet and acts as an _ for pancreatic _ to act on - _ to digest _
co-lipase, anchor, lipase, water-lipid interface, TAG
Pancreatic lipase can be inhibited by high concentration of _ _
Bile salts
Products of TAG hydrolysis
Free Fatty Acids, LCFAs, MCFAs, Monoglycerides, Phospholipids
After lipolysis bile salts form _ by incorporating products of TAG hydrolysis
Micelles
Micelles are able to transport the lipolysis products to UWL so they can be absorbed through the brush border and into the _
enterocyte
LCFAs absorb _ than MCFAs or SCFAs
faster
Lipids enter enterocytes in _ _ form and leave to various tissues as _ through the - region into bloodstream
single molecule, portomicrons, base-lateral
Intracellular transport of lipids involves _ _ _ _ ()
Fatty Acid Binding Protein (FABP)
FABP works better for _, _
Unsaturated, LCFAs
After Fatty Acids are absorbed and transported to the liver packaged into _ and packaged into _ _ _ _ (VLDLs)
TAGs, Very low density lipoproteins
VLDLs are recreated into the bloodstream to go to
Tissues, Meat, Eggs
