Interpretation Introduction

(a)

Interpretation:

Prostaglandin should be labeled as Hydrolyzable or non-hydrolyzable lipid.

Concept Introduction:

Lipids can be grouped as hydrolyzable and nonhydrolyzable. Hydrolyzable lipids can be broken down into smaller molecules by reacting with water. Hydrolyzable lipids usually contain an ester functional group which is hydrolyzable. There are three subgroups of hydrolyzable lipids as waxes, triacylglycerols and phospholipids. Nonhydrolyzable lipids cannot be broken down into smaller molecules by hydrolysis with water. There are subgroups of nonhydrolyzable lipids as steroids, fat-soluble vitamins and eicosanoids.

Answer to Problem 19.29P

Nonhydrolyzable

Explanation of Solution

Prostaglandin is a 20 carbon unsaturated carboxylic acid which contains a five-membered ring. A typical structure for prostaglandin is,

Interpretation Introduction

(a)

Interpretation:

Prostaglandin should be labeled as Hydrolyzable or non-hydrolyzable lipid.

Concept Introduction:

Lipids can be grouped as hydrolyzable and nonhydrolyzable. Hydrolyzable lipids can be broken down into smaller molecules by reacting with water. Hydrolyzable lipids usually contain an ester functional group which is hydrolyzable. There are three subgroups of hydrolyzable lipids as waxes, triacylglycerols and phospholipids. Nonhydrolyzable lipids cannot be broken down into smaller molecules by hydrolysis with water. There are subgroups of nonhydrolyzable lipids as steroids, fat-soluble vitamins and eicosanoids.

Answer to Problem 19.29P

Nonhydrolyzable

Explanation of Solution

Prostaglandin is a 20 carbon unsaturated carboxylic acid which contains a five-membered ring. A typical structure for prostaglandin is,
