Group 9: Fat Metabolism Flashcards
Absorption of Fats, Oxidation of Fats, Glycerols, and Fatty Acids
Location where the interaction with bile occurs.
Small intestine
The site where triacylglycerols are broken down into monoacylglycerols.
Small intestine
What digestive enzyme aids in the breakdown of triacylglycerols to monoacylglycerols.
Pancreatic Lipase
Triacyl glycerols are converted into small droplets caused by the churning action. Where does this take place?
Stomach
A thick, semi-liquid made up of partially digested food and gastric secretions.
Chyme
The site where gastric lipases are active.
Stomach
The site where pancreatic enzymes are active.
Small intestine
Site where fatty acid micelle is produced.
Small intesine
Chylomicrons are produced in:
Intestinal cells
Monoacylglycerols are converted back/repackaged into triacylglycerols.
Intestinal Cells.
Major enzymes responsible for lipid digestion
Pancreatic Lipase
It is a 4- Carbon molecule
a. Ketoacid
b. Lipids
c. Acetoacetate
d. Beta-hydroxybutyrate
e. Both c and d
Acetoacetate and Beta-hydroxybutyrate
It is a ketoacid
a. Acetoacetate
b. Butyric acid
c. Butyrate
d. Amino acid
a. Acetoacetate
Its structure contains a ketone functional group.
I. butyric acid
II. Acetoacetate
III. acetone
IV. Muriatic acid
V. Hydroxybutyrate
a. I. and V.
b. II. and III.
c. V. only
d. I, II, III, IV, and V.
b. II and III
It is classified as a ketone body, but not a ketone.
a. Ketoacid
b. Lipids
c. Acetoacetate
d. Beta-hydroxybutyrate
e. Both c and d
d. Beta-hydoxybutyrate
When are ketone bodies produced?
During excessive amounts of acetyl CoA produced
A metabolic pathway by which fatty acids are synthesized from acetyl CoA
Lipogenesis
Site where lipogenesis occur
Cell cytosol
When does biosynthesis of fatty acids occur?
When dietary sources provide more nutrients than required
The starting material for lipogenesis.
acetyl CoA
It is the hydrolysis of triacylglycerols stored in adipose tissue, followed by the release into the bloodstream of fatty acids and glycerol so produced.
TAG mobilization
It is a TAG-storing cell.
Adipocyte
It is a tissue that contains large number of adipocyte cells.
Adipose tissue
