Ketone Methodology

The ketone measurement is based on the following 

methodology:

                                                      

Enzyme

1. D-3-hydroxybu NAD ––––––> Acetoacetate  
    + NADH + H

+

2. Mediator (ox) + NADH –––––> Mediator (red) + NAD
                                

-e

-

3. Mediator (red) ––––––> Mediator (ox)

The current generated at the electrode is proportional to the 

ketone concentration of the sample.
