Interpretation Introduction

Interpretation:

The structure of triacylglycerol that is found in cocoa butter should be drawn.

Concept Introduction:

Triacylglycerols are most abundant lipids which are mainly found in animal fat and vegetable oils. They are triesters of glycerol.Therefore,in the formation of one molecule of triacylglycerol, three molecules of fatty acids react with one molecule of glycerol as given below:

  ${\text{CH}}_{\text{2}}{\text{(OH)CH(OH)CH}}_{\text{2}}\text{(OH) + 3 R- COOH}\stackrel{}{\to }{\text{CH}}_{\text{2}}{\text{(OCOR)CH(OCOR)CH}}_{\text{2}}{\text{(OCOR) + 3 H}}_{\text{2}}\text{O}$
