Coenzymes redox potentials, table

The oxidation-reduction potential of a pyridine nucleotide coenzyme system is determined by the standard redox potential for the free coenzyme (Table 6-8) together with the ratio of concentrations of oxidized to reduced coenzyme ([NAD+] / [NADH], Eq. 6-64). If these concentrations are known, a redox... 

In Chapt. yi we have discussed the chemical nature of several hydrogen-transferring coenzymes. They are redox systems, because hydrogen transfer is equivalent to electron transfer (Section 2). Other redox systems consist of substrates which react with enzymes and their cosubstrates (= coenzymes) for example, the mixture of alcohol and acetaldehyde (equimolar) can be assigned a standard potential, as can the system succinate-fumarate, and so forth. Redox potentials of this kind are listed in the right-hand half of Table XIV.
