Equality
Description
Physicochemical equality (symbol =) indicates in an equation not only numerical equivalence (symbol ≡), but an identity of the full meaning.
Abbreviation: =
Reference: Gnaiger 2020 BEC MitoPathways
Example
- Iconic symbols indicate equality beyond equivalence, for instance in equations for the protonmotive force pmF (Blue Book Eq. 8.1 and 8.2)
- Conventional symbols:
The protonmotive force pmF Format Definition Units charge format: Δp ≡ ∆𝜇H+ ∙ (𝑧H+ ∙ 𝐹)−1 + ∆𝛹p+ [J∙C-1 = V] amount format: Δ𝜇̃ H+ ≡ ∆𝜇H+ + ∆𝛹p+ ∙ (𝑧H+ ∙ 𝐹) [J∙mol-1 = Jol]
- Iconic symbols: ΔmFH+ = ΔdFH+ + ΔelFp+
Chemical potential, stoichiometry, and metabolic force Quantity Symbol Equation Units Blue Book 8.2.2. potential: μH+ = RT∙ln aH+ = -RT∙ln(10)∙pH [kJ∙mol-1] 8.18a difference ΔμH+ = -RT∙ln(10)∙ΔpH = -RT∙2.303∙(pHb-pHa) [kJ∙mol-1] 8.18b force: ΔdFH+ = μH+a∙νa + μH+b∙νb =-RT∙2.303∙∆dpH [kJ∙mol-1] 8.18c
