comment "For biochemical reactions, this property refers to the standard transformed Gibbs energy change for a reaction written in terms of biochemical reactants (sums of species), delta-G'<sup>o</sup>.
delta-G'<sup>o</sup> = -RT lnK'
and
delta-G'<sup>o</sup> = delta-H'<sup>o</sup> - T delta-S'<sup>o</sup>
delta-G'<sup>o</sup> has units of kJ/mol. Like K', it is a function of temperature (T), ionic strength (I), pH, and pMg (pMg = -log<sub>10</sub>[Mg<sup>2+</sup>]). Therefore, these quantities must be specified, and values for DELTA-G for biochemical reactions are represented as 5-tuples of the form (delta-G'<sup>o</sup> T I pH pMg). This property may have multiple values, representing different measurements for delta-G'<sup>o</sup> obtained under the different experimental conditions listed in the 5-tuple.
