β-VLDL

beta VLDL a mixture of lipoproteins with diffuse electrophoretic mobility approximately that of β-lipoproteins but having lower density; they are remnants derived from mutant chylomicrons and very-low-density lipoproteins that cannot be metabolized completely and therefore accumulate in plasma. Called also floating beta lipoproteins. See also familial dysbetalipoproteinemia.
