For more than a thousand chemical species of biological interest the table gives:

Standard chemical, apparent chemical, and metabolic potentials.
Standard chemical potentials: extracted from various literature refernecs (data sources)
Standard apoparent chemical potentials as the abovew s chemical potentials but further transformed for H+ and ionic strength; for Alberty conditions and for new biochemical conditions
Standard metabolic potential: as above but then further transformed with respect to CNOPS. tuned to mM concentration units.

The standard chemical potentials are much more suitable for biology, biochemistry, metabolic engineering and enzymology. They are good indicators of the biologically relevant Gibbs energy content of the molecules, as their concentration dependent terms are small. The difference in standard metabolic potential between ATP and ADP is for instance very close to 50 kJ, the actual Gibbs energy of ATP synthesis. Along metabolic pathways the standard mertabolic potentials tend to be smooth cascades whereas the standard chemical potentials shoot up and down. The standard metabolic potentials given are for pH=7, pMg=3, I=0.15 M, osmolarity = 0.55 M and a concentration of 1 mM (rather than the physical chemical reference state of pH=pMg=I=Omolarity=0; and 1 M activity) and temperatures of 25 C or 37 C and thereby very close to what is relevant in most biochemical conditions.
