And what that bile does is it basically emulsifies. It mechanically breaks down our lipids into smaller pieces so that our lipase, the proteolytic enzyme, can actually chemically digest and cleave those ester bonds inside the lipids. This process is known as emulsification. So without bile, we would have a lot of trouble actually breaking down our lipids. And once again, all the enzymes that function in the small intestine function at a PH of about 8.5. And what gives it a PH of 8.5, what makes it a basic solution inside the lumen of the small intestine is the bicarbonate that exists in the pancreatic juice.
