The number of ester linkages in the given triacylglycerol molecules have to be predicted. Concept introduction: Triacylglycerol is produced by the reaction of one molecule of glycerol and three molecules of fatty acid. The three hydroxyl groups of glycerol get esterified on reaction with fatty acids.
