Chapter 21, Problem 21.106EP

(a)

Interpretation Introduction

Interpretation: The B vitamin precursor for the coenzyme, ${\text{NAD}}^{\text{+}}$ has to be identified.

Concept introduction: Vitamin-B is a water soluble vitamin.  There are eight vitamins classified as Vitamin B on the basis of their biochemical function to act as a precursor for the enzyme cofactors.  The eight vitamin B are: thiamin, riboflavin, niacin, pantothenic acid, vitamin ${\text{B}}_{\text{6}}$, biotin, folate, vitamin ${\text{B}}_{\text{12}}$.

(b)

Interpretation Introduction

Interpretation: The B vitamin precursor for the coenzyme, FMN has to be identified.

Concept introduction: Vitamin-B is a water soluble vitamin.  There are eight vitamins classified as Vitamin B on the basis of their biochemical function to act as a precursor for the enzyme cofactors.  The eight vitamin B are: thiamin, riboflavin, niacin, pantothenic acid, vitamin ${\text{B}}_{\text{6}}$, biotin, folate, vitamin ${\text{B}}_{\text{12}}$.

(c)

Interpretation Introduction

Interpretation: The B vitamin precursor for the coenzyme, FAD has to be identified.

Concept introduction: Vitamin-B is a water soluble vitamin.  There are eight vitamins classified as Vitamin B on the basis of their biochemical function to act as a precursor for the enzyme cofactors.  The eight vitamin B are: thiamin, riboflavin, niacin, pantothenic acid, vitamin ${\text{B}}_{\text{6}}$, biotin, folate, vitamin ${\text{B}}_{\text{12}}$.

(d)

Interpretation Introduction

Interpretation: The B vitamin precursor for the coenzyme THF has to be identified.

Concept introduction: Vitamin-B is a water soluble vitamin.  There are eight vitamins classified as Vitamin B on the basis of their biochemical function to act as a precursor for the enzyme cofactors.  The eight vitamin B are: thiamin, riboflavin, niacin, pantothenic acid, vitamin ${\text{B}}_{\text{6}}$, biotin, folate, vitamin ${\text{B}}_{\text{12}}$.
