So we have a small green protein, we have an intermediate size red protein, and we have a large protein. Now, those tiny proteins, because of their small size, they will be able to fit into the internal structure of these beads. And so what that means is these tiny green proteins will be able to fit into the crevices, the pores inside our bead, and they will spend more time traveling inside our bead, these red intermediate proteins, because of their slightly larger size, sometimes they will be able to fit into the pores, but sometimes they will not. And as a result, because they spend less time moving inside the crevices of our bees, they will travel quicker along our column as compared to these tiny proteins. And if we examine this very large protein, shown a purple, these proteins will not be able to fit into the tiny pores, into the internal structure, the volume of those beets. And so they will never travel inside the bead and always move around the bead.
