Cholesterols

Question 1

lipoprotein

Answer 1

apoprotein + lipid. Lipids bind to apoproteins so be soluble in plasma

Question 2

High-density lipoproteins (HDL):

Answer 2

about half protein and half lipid, and most of their lipid is phospho- lipid and cholesterol. HELPFUL

Question 3

Low-density lipoproteins (LDL):

Answer 3

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.

Question 4

Very-low-density lipoproteins (VLDL):

Answer 4

only about 10% protein, and most of their lipid is triglycerides, with smaller amounts of phospholipid and cholesterol

Question 5

Chylomicrons

Answer 5

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

Question 6

Benefits of lowering cholesterol

Answer 6

• 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

Question 7

High triglyceride amplifies

Answer 7

amplifies the vascular risk of high LDL cholesterol or low HDL cholesterol

Question 8

Total cholesterol below 200mg/dl

Answer 8

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)

Question 9

HDL, LDL, causation/marker

Answer 9

High LDL is causative - it causes atherosclerosis

High HDL is associative - it is associated with lower risk of vascular disease - “marker”

Question 10

Dont focus on reducing your fat consumption

Answer 10

change the type of fat you consume. unsaturated, liquid at room temp = good,
saturated, solid at room temp = bad

Question 11

desirable cholesterol values

Answer 11

total <200
HDL >60
LDL <100
Triglyceride <150
