Flashcards in Cholesterols Deck (11)

1
lipoprotein
apoprotein + lipid. Lipids bind to apoproteins so be soluble in plasma
2
High-density lipoproteins (HDL):
about half protein and half lipid, and most of their lipid is phospho- lipid and cholesterol. HELPFUL
3
Low-density lipoproteins (LDL):
only about 22% protein, and most of their lipid is cholesterol, with smaller amounts of phospholipid and triglycerides. LOUSY. Causative, that is, it actually causes atherosclerosis.
4
Very-low-density lipoproteins (VLDL):
only about 10% protein, and most of their lipid is triglycerides, with smaller amounts of phospholipid and cholesterol
5
Chylomicrons
exceedingly small lipid droplets that pass from bowel mucosa into intestinal lymphatics, which dump them into the bloodstream, about 85% triglyceride, cleared from plasma by the liver
6
Benefits of lowering cholesterol
-Decreasing total cholesterol by 50 mg/dL cuts in half the risk of dying from a heart attack
-Evidence suggests that atherosclerosis may not develop with total cholesterol levels below 150 mg/ dL
7
High triglyceride amplifies
amplifies the vascular risk of high LDL cholesterol or low HDL cholesterol
8
Total cholesterol below 200mg/dl
is considered desirable for good health, and the lower the better: lowering total cholesterol has benefits at almost any initial cholesterol level (any starting point)
9
HDL, LDL, causation/marker
High LDL is causative - it causes atherosclerosis
High HDL is associative - it is associated with lower risk of vascular disease - "marker"

Dont focus on reducing your fat consumption
change the type of fat you consume. unsaturated, liquid at room temp = good,
saturated, solid at room temp = bad
