Is Apoprotein A1 present on chylomicrons?

First aid says is it, but since it's function is to activate LCAT, i don't understand what it's use would be on chylomicrons?

It is, but all i could find online is that while chylomicrons have A1, it's quickly transferred to HDL so i think just associate it with HDL, knowing chylomicrons also have them.

Yeah I think ApoA is on the surface of HDL and activates LCAT to put the fatty acid onto the IDL cholesterol making cholesterol ester. The cholesterol ester is just transferred back to IDL in circulation.
