Now, as we'll see in just a moment, these apoproteins are used to actually recognize this kylomicrine. They are used to attach onto special receptor proteins found on the membrane of certain target cells. So the majority of the fats or lipids inside the sites, inside the cells of the small intestine, are stored and packaged in these particles known as kylomycrans. Now, notice, the kylomycran is not a molecule, but a particle. And the difference is, a particle consists of thousands of these different molecules. So inside we have thousands of these fat molecules.
