NURS 549 Week 2 Lipids - Statins Test
With Complete Solution
Lipid management - ANSWER concern for atherosclerotic plaque
lipid - ANSWER any physiologic substance that is fat-soluble
most lipids are good
cholesterol - ANSWER building block
primary structural compound of cell membrane
precursor to bile salts and steroid horomones
triglyceride (fatty acid/triaglycerol) - ANSWER major fuel source
3 fuel sourcs - ANSWER carbs (glucose)
protein (aminoacids)
fat (triglycerides)
glycerophospholipids/sphingolipids - ANSWER lipid molecules embedded in
cell membrane
give ability to interact with water
provide hydrophobic barrier between H2O and cholesterol
eicosanoids - ANSWER precursor to prostaglandins
bile salts - ANSWER help emulsify dietary fats
fat has to be broken down by lining of small intestine, bile breaks it down.
,built from cholesterol
steroid hormones - ANSWER glucocorticoids
mineral corticoids
sex hormones
assembled with cholesterol and other parts
fat soluble vitamins - ANSWER A vision
D calcium/phosphorous balance
E antioxidant -lots of cellular damage is oxidative
K intrinsic to clotting
main 2 lipids important in cardiovascular disease - ANSWER triglycerides and
cholesterol
either ingested or synthesized
triglycerides pathway - ANSWER start in gut if eaten
start in liver if made
then travel through plasma to muscle to be burned as fuel or adipose for fat
storage
, cholesterol pathway - ANSWER housed in free-cholesterol pool in liver to
make structures when needed
when eaten, has to go from gut to liver and travel through plasma
triglyceride ingestion - ANSWER major dietary lipid
have to be packaged in a way to move through plasma to avoid fat embolis.
requires mobilization
small intestine breaks it down -emulsified by bile salts -stored in gallbladder
-ejected into gut
lipase - ANSWER helps bile salts break down triglycerides into purest form
(monoacylgycerols and free fatty acids)
free fatty acids - ANSWER absorbed into intestinal epithelial cells then
reassembled to be used back in trigylceride form
intestinal epithelial cell inside - ANSWER reassembled triglyceride packaged
