1
Q
What is the order of lipoproteins from most to least dense?
A
HDL>LDL>VLD>chylomicrons
2
Q
Why are chylomicrons the least dense lipoprotein?
A
They are the largest and least dense because they contain the most TAGs. VDLs contain more protein that chylomicrons are so are more dense than chylomicrons
3
Q

A
Triglycerides - reflects the fact that they are the main constituent of dietary lipids and chylomicrons transfer dietary lipids to the liver
4
