Morphology

high-density + lipoprotein

This is a straightforward compositional noun phrase: 'high-density' (high + density) modifies 'lipoprotein' (a protein that carries lipids), so the meaning is a lipoprotein that has relatively high density (more protein vs. lipid). A B1 learner who knows the constituent meanings can infer this technical but predictable relationship, and the modifier-noun logic is cross-linguistically regular.

Etymology

High-density lipoprotein comes from its literal parts: high-density means packed and heavier, and lipoprotein is a small carrier of fat and protein in the blood. Because these dense carriers pick up extra cholesterol and take it away from blood vessels, they are the 'good' kind that help protect the heart.
