Interpretation Introduction

Interpretation:

The condensed structural formula of the mixed triacylglycerol formed from the reaction of glycerol with two molecules of palmitic acid one molecule of oleic acid should to be deduced.

Concept introduction:

► Esters are characterised by the presence of – $\text{COO}$ functional group and are formed form the reaction of carboxylic acids ($\text{RCOOH}$) with alcohols ($\text{ROH}$). The process is termed as esterification.

► Since the reaction proceeds with the loss of a molecule of water, it is also referred to as a condensation reaction

► Similarly, triacylglycerols are esters of glycerol (which is a trihydroxy alcohol) and fatty acids. They are formed when the three hydroxyl groups of glycerol react with the carboxylic group of three fatty acids accompanied by the loss of three molecules of water.
