WebStructure of fats and oils. All fats and oils are naturally occurring esters, formed from condensation reactions between the alcohol glycerol and different long chain carboxylic acids (fatty acids). Glycerol is also known by its systematic name propane-1,2,3-triol. It is a triol, meaning that it has three hydroxyl functional groups.
