How are fats absorbed and transported by the body?

Well, they get absorbed where all the other nutrients get absorbed as well, with the exception of fiber...


Lipids and fats are unabsorbed until they reach the small intestine, where they meet bile and enzymes such as lipase, which break them down into fatty acids and glycerol for absorption and assimilation.

Bile emulsifies the fats, which means that it breaks it down into smaller pieces to increase the surface area, which increases the rate of an enzyme breaking it down and absorption.

Since lipids are mostly nonpolar and are not transported well by water, special proteins called lipoproteins in our blood help transport them around our body.
