Q

What are phosphilipids?

A

Like triglycerides, phospholipids have a glycerol backbone. But unlike triglycerides, phospholipids
only have two fatty acid molecules attached to the glycerol backbone. In place of the third fatty
acid chain, phospholipids have a phosphate group. This unique structure makes one end of
phospholipids water-soluble and the other end fat-soluble.
