Chapter 27.6, Problem 17WDYL

Summary Introduction

To determine:

The molecular structure out of ( $\text{VLDLs}$, $\text{LDLs}$, and $\text{HDLs}$) responsible for the transportation of cholesterol from peripheral tissues to the liver.

Concept introduction:

Cholesterol molecules are not soluble in blood, so the cholesterol molecules can only be transported with the help of “water-soluble proteins”. There are three types of proteins for the transportation of lipids through the blood: $\text{VLDLs}$ “Very low-density lipoproteins”, $\text{LDLs}$ “Low-density lipoproteins”, $\text{HDLs}$ and “High-density proteins”.
