In the field of molecular biology, apolipoprotein C is a family of four low molecular weight apolipoproteins, designated as C-I, C-II, C-III, and C-IV.
These are surface components of chylomicrons, VLDL, and HDL.
When an organism is in the fasting state, the C apolipoproteins are mainly associated with HDL.
But during absorption of dietary fat, the C apolipoproteins preferentially redistribute to the surface of the triglyceride-rich chylomicrons and VLDL.
