Remnant Lipoprotein Unit Converter

Remnant lipoprotein cholesterol is the cholesterol carried by triglyceride-rich lipoprotein particles after they have delivered fatty acids to tissues. These particles include very low-density lipoprotein (VLDL) remnants, intermediate-density lipoproteins (IDL), and chylomicron remnants.

It is calculated from a standard lipid panel as total cholesterol minus LDL cholesterol minus HDL cholesterol. This captures all cholesterol not accounted for in the LDL and HDL fractions.

Each remnant particle contains roughly 40 times more cholesterol than an LDL particle. Growing evidence suggests remnant cholesterol is a strong independent predictor of cardiovascular disease risk, even in people whose LDL cholesterol is well controlled.

Remnant lipoproteins form when triglyceride-rich particles from two sources deliver their fatty acids to tissues. The liver produces VLDL, which is partially broken down into IDL remnants, while the intestines produce chylomicrons from dietary fats, which become chylomicron remnants after triglyceride removal.
