Lipid Metabolism Flashcards
hormone that triggersr the release of bile
cholecystokinin
major enzyme invovled in small intestine that hydrolyzes ester link between glycerol and fatty acid
pancreatic lipase
The major change that TAGs undergo in the stomach is ___ rather than chemical.
physical
action of the stomach breaks up triacylglycerol materials into small globules
churning
a thick semi-liquid material made up of small triacylglycerol globules, other partially digested food, and gastric secretions (hydrochloric acid and several enzymes)
chyme
With the help of bile, the free fatty acids and monoacylglycerols produced from hydrolysis are combined into tiny spherical droplets called ___
they are very small compared to the original triacylglycerol globules, which contain thousands of triacylglycerol molecules
micelles
The newly formed triacylglycerols are then combined with membrane lipids (phospholipids and cholesterol) and water-soluble proteins to produce a type of lipoprotein
chylomicron
since chylomicron is large, the delivery of the chylomicrons to the bloodstream is accomplished through
lymphatic system
a triacylglycerol-storing cell.
adipocyte
Use of the TAGs stored in adipose tissue for energy production is triggered by two hormones namely;
ephinephrine and glucagon
The overall process of tapping the body’s triacylglycerol energy reserves (adipose tissue) for energy is called
triacylglycerol mobilization
the site of fatty acid activation
mitochondrial membrane
The activated fatty acid-CoA molecule
acyl coa
