Answer to Problem 22.50E

The balanced reaction for OHCH2COOHO=CHCOOH oxidations using NAD+ is shown below.

OHCH2COOH+NAD+O=CHCOOH+NADH.

Explanation of Solution

The oxidation reaction is given as OHCH2COOHO=CHCOOH.

In the above reaction, the alcohol group is oxidized to aldehyde group. The oxidation reaction by NAD+ involves the oxidation of alcohol into aldehyde. Therefore, the oxidation reaction is balanced by using NAD+ as shown below.

OHCH2COOH+NAD+O=CHCOOH+NADH

Conclusion

The balanced reactions for OHCH2COOHO=CHCOOH oxidations using NAD+ is shown below.

OHCH2COOH+NAD+O=CHCOOH+NADH.

Interpretation Introduction

Answer to Problem 22.50E

The balanced reaction for OHCH2CH2OHOHCH=CHOH oxidations using FAD is shown below.

OHCH2CH2OH+FADOHCH=CHOH+FADH2.

Explanation of Solution

The oxidation reaction is given as OHCH2CH2OHOHCH=CHOH.

In the above reaction, the CH2CH2 portion of 1, 2-diethanol is oxidized to CH=CH. The oxidation reaction by FAD involves the conversion of CH2CH2 into CH=CH. Therefore, the oxidation reaction is balanced by using FAD as shown below.

OHCH2CH2OH+FADOHCH=CHOH+FADH2

Conclusion

The balanced reaction for OHCH2CH2OHOHCH=CHOH oxidations using FAD is shown below.

HOCH2CH2OH+FADHOCH=CHOH+FADH2.
