Lipoprotein, illustration. This is a high density lipoprotein (HDL), or 'good' cholesterol, molecule. It consists of a core of esterified cholesterol molecules surrounded by a shell of unesterified cholesterol (orange with violet cap) and phospholipids (orange with blue cap). The complex structure includes carrier proteins (green) known as apolipoproteins, which assist transport in the blood. HDL cholesterol plays a role in fat metabolism and contributes to cardiovascular health.
