Low-density lipoprotein, a type of cholesterol-carrying particle in the blood often called 'bad cholesterol'. High levels are associated with cardiovascular disease risk.
Medical acronym from the 1970s, formed from 'low-density lipoprotein'. The term reflects the particle's physical properties - it has less protein relative to lipids than HDL, making it less dense when separated by centrifugation.
LDL isn't actually cholesterol itself - it's like a tiny delivery truck carrying cholesterol through your bloodstream! The 'bad' reputation comes from its tendency to dump cholesterol in artery walls when there's too much traffic, like a delivery truck getting stuck in a traffic jam.
