This transfer is arbitrarily annotated here as involving one molecule of each apolipoprotein. The molecular difference that enables nascent chylomicrons to accept apolipoproteins from sperical HDL and TG-depleted chylomicrons to donate them is unclear. spherical HDL:apoA-I:apoA-II:apoA-IV:apoC-II:apoC-III chylomicron remnant TG-depleted chylomicron spherical HDL
