Lipoprotein

Question 1

Type of the lipoprotein based on the density

Answer 1

Chylomicrons (B-48)

Very Low density lipoprotein (VLDL) (B-100)

Low density lipoprotein (LDL) (B-100)

High density lipoprotein (HDL) (Apo-A)

Question 2

Function of chylomicrons

Answer 2

Transfer exogenous triglycerides (TG) from intestines to the adipose tissues (storage) and muscle/heart (energy)

Question 3

Function of Very Low density lipoprotein (VLDL) (B-100)

Answer 3

Transfer endogenous triacylglycerol (TAG) from the liver to peripheral tissues (energy)

Question 4

Function of Low density lipoprotein (LDL) (B-100)

Answer 4

Transport cholesterol from liver to peripheral tissues

Question 5

Function of high density lipoprotein (HDL) (Apo-A)

Answer 5

1) Reservoir of apoproteins (apo-C II & apo-E)

2) HDL uptake of unesterified cholesterol
-it is the reverse of cholesterol transport, it transfer cholesterol from peripheral tissue to liver and excrete through bile

3) Esterification of cholesterol
- cholesterol esterified to cholesteryl ester and help to transport cholesterol out the blood and tissue

E:Lecithin cholesterol acyl transferase (LCAT)
