Skeleton structure of fatty acid A with cis double bond has to be drawn. Concept Introduction: Fatty acid leads to formation of lipids and consists of a carboxyl group ( − COOH ) with long straight chain of carbon and hydrogen atoms. Long straight-chain can be saturated as well as unsaturated. They comprise of a hydrophobic and hydrophilic part in their structure. The nonpolar or hydrophobic part of the chain consists of hydrocarbons that are insoluble in water. Therefore, fatty acids are not soluble in water.

Answer 1

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.

(a)

Interpretation Introduction

Interpretation:

Skeleton structure of fatty acid A with cis double bond has to be drawn.

Concept Introduction:

Fatty acid leads to formation of lipids and consists of a carboxyl group (−COOH) with long straight chain of carbon and hydrogen atoms. Long straight-chain can be saturated as well as unsaturated. They comprise of a hydrophobic and hydrophilic part in their structure. The nonpolar or hydrophobic part of the chain consists of hydrocarbons that are insoluble in water. Therefore, fatty acids are not soluble in water.

(b)

Interpretation Introduction

Interpretation:

The omega-n designation for fatty acid A has to be identified.

Concept Introduction:

Fatty acids with unsaturation are classified as omega-n acids; here n is the carbon number from that the beginning of first double bond occurs in a carbon chain.

(c)

Interpretation Introduction

Interpretation:

Stereoisomer of fatty acid A has to be drawn.

Concept Introduction:

Some molecules have similar molecular structure but differ in the spatial arrangement of atoms that is atoms are located differently in space. Such molecules are termed as stereoisomers.

(d)

Interpretation Introduction

Interpretation:

Structure of wax formed from fatty acid A and CH3(CH2)10OH has to be drawn.

Concept Introduction:

Waxes are the type of nonpolar lipids that contain esters and are formed by the reaction of carboxylic acid with long chain alcohol by the removal of water. Generally, waxes are extracted from plants and animals. The reaction that explains the formation of wax is as follows:

Here, R and R′ are different alkyl groups.
