LIPOPROTEIN PHYSIOLOGY AND METABOLISM Flashcards
❖ Happen and absorbed in the small intestine
❖ Enhanced by emulsifying agents such as bile salts / acids
A. EXOGENOUS PATHWAY
B. LIPID ABSORPTION
C. REVERSE CHOLESTEROL TRANSPORT PATHWAY
D. ENDOGENOUS PATHWAY
B. LIPID ABSORPTION
Conversion of dietary lipids into more polar or more absorbable form (amphipathic) compounds
A. EXOGENOUS PATHWAY
B. LIPID ABSORPTION
C. REVERSE CHOLESTEROL TRANSPORT PATHWAY
B. LIPID ABSORPTION
lipid absorbtion
Triglyceride will be converted to
a. polyglycerides
b. Monoglycerides
b. Monoglycerides
responsible for converting the lipids in the
diet into more polar compound to facilitate absorption
a. Pancreatic Lipase
b. Chylomicrons
c. Lipoprotein Lipase (LPL)
d. Triglycerides in the liver
a. Pancreatic Lipase
Cholesterol esters will be converted to →
a. free cholesterol
b. Chylomicrons
c. Lipoprotein Lipase (LPL)
d. Triglycerides in the liver
a. free cholesterol
Phospholipids can be converted to
a. free cholesterol
b.lysophospholipids
c. Lipoprotein Lipase (LPL)
d. Triglycerides in the liver
b.lysophospholipids
the enzyme that will hydrolyzes triglycerides
in the chylomicrons into Fatty Acids and Glycerol or re esterified for long term storage in the hepatic cells
a. Lipoprotein Lipase (LPL)
b. Pancreatic Lipase
a. Lipoprotein Lipase (LPL)
Triglycerides in the liver
a. endogenous pathway
b exogenous pathway
a. endogenous pathway
in endogenous pathway
**VLDL is converted into: VLDL remnants by action of _ and taken up by liver **
a. Lipoprotein Lipase (LPL)
b. Pancreatic Lipase
a. Lipoprotein Lipase (LPL)
HDL remove excess cholesterol transport pathway deliver cholesterol to the liver

TRANSPORT PATHWAY
**HDL can also be obtained in the diet like **
a. fish oils
b. omega 6
c. omega 3
d. omega 5
a, b and c
HIGH HDL CAN RESULT TO
A. LOW RISK FOR CORONARY HEART
B. HIGH RISK FOR HART DISEASE
A. LOW RISK FOR CORONARY HEART
