Summary Introduction
To determine:
The molecular structure out of (
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:
