Low density lipoprotein structure, animation. Low density lipoprotein (LDL), or 'bad' cholesterol, is a biochemical assembly that consists of a core of esterified cholesterol molecules surrounded by a shell of unesterified cholesterol and phospholipids.

This narrows the blood vessels and may block them
