Dear Shu-Kun:

A brief response to your message before departing on an extended trip.

I do not understand what you mean when you write:
 
>
>The equilibrium constant is the the symmetry number of the product over the
>symmetry numberof the starting molecules.

Would you give a practical example using NAD, Nicotinamide Adenine
Dinucelotide (C21H27N14O7P2)? Consider the reaction catalysed by
alcohol dehydrogenase. This is the same molecule that Karl and I have
used to explore his views.

I know you are very busy and I will be traveling, so take your time
to think about this example and reply in a few weeks.

Cheers

Jerry
