Question 1

What does LDL (low density lipoprotein) do?

Answer 1

carries cholesterol to the walls of the arteries, forming atherosclerotic plaques.

Question 2

Composition ratio of LDL (low density lipoprotein)?

Answer 2

higher percentage of cholesterol and a lower percentage of apoprotein

Question 3

Normal LDL level

Answer 3

190: Very high

*ratio of LDL/HDL is more important

Question 4

Total Cholesterol

Answer 4

cell membranes, steroid hormones and bile acids. In the blood, cholesterol is carried by three different lipoproteins: HDL, LDL and VLDL.

Question 5

Normal Lvl of Total Cholesterol

Answer 5

A measurement less than 200 mg/dL is desirable

Question 6

VLDL - Very Low Density Lipoprotein

Answer 6

triglycerides/5

Question 7

Normal range of VLDL - Very Low Density Lipoprotein

Answer 7

No “normal” ranges, but VLDL level inversely related to HDL levels, making an elevated VLDL a predictor of CHD.

Question 8

Function/Storage of Triglycerides

Answer 8

Main portion of VLDL,
Stored in fat cells for energy (main form of lipid storage).
Rise after fatty meal.

Question 9

Density of chylomicrons relative to other lipoproteins

Answer 9

Lowest density lipoprotein.

Question 10

Normal levels of Triglycerides

Answer 10

Normal: /=500 mg/dL

Question 11

Normal Chylomicron lvls

Answer 11

normally not measured

Question 12

What is Lipoprotein A [LP(a)], what can it cause/how?

Answer 12

LDL-like particle with structure similar to plasminogen. Contributes to atherosclerosis and is also prothrombotic because it can displace plasminogen from its binding sites. Does not respond to statin therapy.

Question 13

Normal lvls of Lipoprotein A [LP(a)]?

Answer 13

PA14 has “Normal: <30 mg/dL,” but neither Current nor other required texts place a number here.
