Chapter 18, Problem 18.19E

Interpretation Introduction

(a)

Interpretation:

The equation for the reaction of Lipase-catalyzed hydrolysis of oil is to be stated.

Concept introduction:

The hydrolysis of the triglycerides in the fat cells results in the formation of fatty acids and glycerol. Lipase-catalyzed hydrolysis involves the hydrolysis of the fats and oils in the presence of lipase catalyst to form glycerol and fatty acids.

Interpretation Introduction

(b)

Interpretation:

The equation for the reaction of saponification of oil is to be stated.

Concept introduction:

The reaction of an ester with a strong base is called saponification reaction. In saponification reaction, the ester bond breaks and results into two products: the salt of carboxylic acid and an alcohol.

Interpretation Introduction

(c)

Interpretation:

The equation for the reaction of hydrogenation of oil is to be stated.

Concept introduction:

The addition of ${\text{H}}_{\text{2}}$ in the presence of catalyst is known as catalytic hydrogenation reaction. This is a syn addition. Hydrogenation reaction is exothermic in nature due to the fact that the bonds are stronger in product than in the reactant.
