1a thick semi-liquid material made up of partially digested food and gastric secretions
chyme
2begins in the stomach
LIPID DIGESTION
3Hydrolysis of TAGs occur with the help of an enzyme known as
gastric lipase
4solubilizes“droplets
bile
5A micelle in which fatty acids and/or monoacylglycerols and some bile are present.
Fatty Acid Micelle
6Small compared to original
TAGs globules
fatty acid micelle
7Lipoprotein that transports TAGs from the intestinal cells, via the lymphatic system, to the bloodstream
chylomicron
8no effect on digestion
saliva
9step by step process of lipid metabolism
1. mouth, 2. stomach, 3. small intestine, 4. intestinal cells, 5. lympatic system, 6. bloodstream
10it produces chyme
churning action
11other name of chyme
small fat droplets
12hydrolyze some 10% TAGS
gastric lipase
13enzyme present in small intestine
pancreatic lipase
14enzyme present in stomach
gastric lipase
15hormone that trigger bile
cholecystokinin
16from stomach - small intestine
some monoacylglycerols
fat droplets in chyme
17it produce monoacylglycerols, which form fatty acid micelles
pancreatic lipase
18from small intestine - intestinal cells
monoacylglycerols in micelles
19it repackages into TAGs , which form chylomicrons
micelles
20from intestinal cells- lympatic system
TAGs in chylomicron
21from lympatic system - Bloodstream
TAGs in bloodstream
22transports to bloodstream
lympatic system
23TAGs are hydrolyzed to free fatty acid
bloodstream
24when glucose breaks down it would form
2 pyruvate
25The fatty acid must be repeatedly oxidized, cycling through a series of four reactions, to produce ___,___ and ____
acetyl CoA,
FADH2 & NADH
