lipoproteins
Blood fat transporters
Lipoproteins are molecular complexes that transport fats through the bloodstream.
Since fats don't dissolve in blood, they're wrapped in protein shells for transport.
The main types—HDL, LDL, VLDL—differ in density and function.
LDL (bad cholesterol) deposits fat in arteries; HDL (good cholesterol) carries it away.
Her lipoproteins were in the healthy range.
