<h3>Lipoproteins</h3>
Explanation:
Lipoproteins are aggregate molecules of lipids and proteins which carry cholesterol in the blood. Cholesterol binds with water-soluble carrier molecules of the lipoproteins.
Based on their density, lipoproteins are classified as very low density lipoproteins (VLDL), low density lipoprotein (LDL), high density lipoprotein (HDL)
