“…In this letter we show our analysis of the data of Frelka et al. () to explain the reverse stability of oxymyoglobin in terms of thermodynamics using transition‐state theory, which has been used in the thermo‐kinetic analysis of chemical reactions in agricultural and food chemicals (Brock, Rosa, & Kang, ; Farhoosh, ; Fisher, Purnell, & Kang, ; Mock & Kang, ; Nayak, Berrios, Powers, & Tang, ; Tang & Skibsted, ). We also discuss an inconsistency found in the original paper and suggest a follow‐up experiment that will allow us to develop a deeper understanding of the oxidation process.…”
