And once we form these molecules, only then can these molecules actually be absorbed by the cells found in our small intestine. So our small intestine doesn't actually or the cells of the small intestine doesn't actually absorb the triathylglycerides. Instead, it absorbs these types of molecules, the constituents, the fatty acids and the monoastylglycerol. Now, the problem is, because of the fact that this is a non polar molecule and our aluminum is predominantly an aqueous environment, we form these large fat globules. And the lipase enzymes can't actually get to the majority of these triglycerides because they exist at the center of the fat globules. And so our liver basically uses cholesterol molecules to help build bile salts.
