Structure of Olestra®

Olestra® is an ester of sucrose and six, seven or eight fatty acids. Here is the FDA "backgrounder" on olestra.
Because of the possibility that hardware limitations may cause difficulties in viewing six structures simultaneously, this page has been split in two. To see the structure of olestra® forthwith, click here.

"Natural" fats are triglycerides, that is, esters of glycerine (1,2,3-propanetriol) and three fatty acids. (For simplicity I have used stearic acid, an eighteen-carbon fatty acid derived from animal fat or palm oil; obviously natural fats contain a range of fatty acids. Olestra®, however, is probably made using only stearic acid, which is cheap and readily available.)
