^aFree energy changes = −RTℓnK_eq(J). R = 8.314 JK⁻¹ mol⁻¹. T = 310 K.

^bK_eq′ is a pseudoequilibrium constant. K is the amount of outer membrane concentration defined in Table 5.

^cValue of ΔG₃ was exampled by the largest value (of deoxyschisandrin) among these three lignans (be referred to Table 2).

^dThe value K_eq in calculation of ΔG_0,4 in reality is not an equilibrium constant because reversible reaction does not occur in the intracellular degradation process. The value was estimated by the difference between the initial and the final conditions (be referred to text).
