Chemistry - Biomolecules Question with Solution | TestHub

Fats and oils are naturally occurring esters of long-chain carboxylic acids (fatty acids) and the trihydric alcohol, glycerol (propane-1,2,3-triol).

Because they are formed from one molecule of glycerol and three molecules of fatty acids, they are specifically known as triglycerides or triesters of fatty acids and glycerol.

Answer: These are triesters of fatty acids and glycerols.
