Now, as soon as we break down, the emulsion droplet into these fatty acids. The fatty acids themselves are hydrophobic, so they cannot exist in the solution of the lumen by themselves. So what happens is the amphithatic phospholipids and the bile salts that are secreted with the bile basically create a spherical structure around those fatty acids, and the structure is known as a myosphil. So, once again, let's take one of these emulsion droplets. As shown, this blue section is the pancreatic lipase. This orange section is the colipase that allows the lipase to bind onto our surface.
