Chapter 20, Problem 20.84P, 4 Below is the structural formula of coenzyme A, an important biomolecule. (a) Is coenzyme A chiral? , example  2

Interpretation Introduction

(a)

Interpretation:

Whether coenzyme A is chiral is to be predicted.

Concept Introduction:

Coenzymes are derived from Vitamins. They are the substance required in small amounts for the normal functioning of the body that the body cannot synthesize in adequate amounts. They are non-proteins molecules which help enzymes for catalyzing the reaction.

A carbon atom that has four nonequivalent atoms or groups attached to it is known as chiral carbon atom. Chiral carbon centers are also called as asymmetric or stereogenic centers.

Explanation of Solution

The structure of coenzyme A is shown below.

Interpretation Introduction

(b)

Interpretation:

The names of each functional group in coenzyme A are to be stated.

Concept Introduction:

Coenzymes are derived from Vitamins. They are the substance required in small amounts for the normal functioning of the body that the body cannot synthesize in adequate amounts. They are non-proteins molecules which help enzymes for catalyzing the reaction.

An atom or a group of atoms that show characteristic physical and chemical properties are collectively known as functional groups. The functional group is the most reactive part present in the molecule. The main functional groups are: OH (alcohol group), COOH (carboxylic acid group), CHO (aldehyde group) and C=O (ketone group).

Interpretation Introduction

(c)

Interpretation:

An explanation corresponding to the solubility of coenzyme A in water is to be stated.

Concept Introduction:

Coenzymes are derived from Vitamins. They are the substance required in small amounts for the normal functioning of the body that the body cannot synthesize in adequate amounts. They are non-proteins molecules which help enzymes for catalyzing the reaction.

Interpretation Introduction

(d)

Interpretation:

The structural formulas for the products of the complete hydrolysis of coenzyme A in aqueous HCl solution showing the ionization of each product are to be drawn.

Concept Introduction:
