Interpretation Introduction

(a)

Interpretation:

The products of hydrolysis of given triacylglycerol needs to be determined.

  

Concept Introduction:

Lipids are biomolecules which are involved in different biochemical reactions. They are special types of organic molecules which can only identify with the help of their physical properties, not by the presence of any certain functional group. In general, lipids contain a large number of C-C and C-H bonds with few polar functional groups such as $\text{–OH, -SH}$ , etc.

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;

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