Fig. 3: Simple model of ribose isomerisation in a steady temperature gradient (T2 > T1).

The highest-energy linear species has energy EL, αF and βF have been coalesced into the high-energy state F (energy EF), while αP and βP are coarse-grained into the ground state (and reference energy), EP. Chemical rates are expressed as the product of a velocity, μ, and an Arrhenius term that depends on the energy barriers ΔEσ (σ = F, P) and include entropic degeneracy factors, ησ, in accordance with our experimental findings.
