lipids Flashcards
high lvls of which lipoprotein class are associated with decreased risk of accelerated atherosclerosis
- chylomicrons
- VLDL
- LDL
- HDL
HDL
which of the following lipid results would be expected to be falsely elevated on a serum specimen from a non-fasting patient?
- cholesterol
- triglyceride
- HDL
- LDL
triglyceride
Turbidity in serum suggests elevation of:
- total protein
- albumin
- cholesterol
- chylomicrons
chylomicrons
The function of the major lipid components of the very-low density lipoproteins (VLDL) is to transport
- cholesterol from the peripheral cells
- cholesterol and phospholipids to peripheral cells
- exogenous triglycerides
- endogenous triglycerides
endogenous triglycerides
lipoprotein structure
spherical formation of lipids and proteins for delivery of internal cargo
what do chylomicrons transport and to where
exogenous triglycerides to the liver (adipose tissue)
apolipoprotein marker for chylomicrons
Apo B-48
describe VLDL
- what it transports
- where it is made
- apolipoprotein marker
- endogenous triglycerides during fasting state
- made in liver
- Apo b-100, E, C-2, C-3
descibe LDL
- what it transports
- how it is made
- made from VLDL w/in blood circulation
- transports cholesterol from liver to organs
how can LDL damage cells
OX reaction as it passes cell walls damages cells, allowing other LDL to adhere and buildup plaque
describe HDL
- what it transports
- where it is made
- made by liver and intestines
- reverse cholesterol transport
- removes excess LDL from cells
what diseases is lipoprotein X seen in
- biliary cirrhosis
- cholestasis
list the 4 main lipid metabolism pathways
- absorption
- exogenous
- endogenous
- reverse cholesterol
describe the absorption lipid metabolism pathway
dietary lipids are recived and broken down by amylase and converted to monosaccharides to pass through intestinal microvilli
describe the exogenous lipid metabolism pathway
after passing through intestine food material is packed into chylomicrons to transport to liver via LPL
