Electrophoretic mobility: which lipoprotein shows alpha mobility?

Explanation:
In lipoprotein electrophoresis, separation is based on size and surface charge. The smallest and most dense lipoprotein, HDL, moves fastest toward the positive electrode and aligns with the alpha globulin region, giving it alpha mobility. Chylomicrons are so large they stay essentially at the origin, VLDL migrates to a pre-beta region between origin and beta, and LDL tends to migrate with the beta globulin region. Therefore, the lipoprotein that shows alpha mobility is HDL.
