The sedimentation nomenclature associated with alpha-lipoprotein is which lipoprotein class?

Explanation:
Alpha-lipoprotein name comes from how these particles move during electrophoresis: they migrate with the alpha-globulins toward the anode. That mobility hallmark identifies high-density lipoproteins. HDL are the smallest, most protein-rich and densest lipoproteins, which is why they’re labeled with alpha in this nomenclature. In contrast, other lipoproteins occupy different regions (for example, LDL as beta-lipoprotein and VLDL as pre-beta, with chylomicrons remaining near the origin), but the alpha designation specifically points to HDL.
