Phenols 11-18 IK cytokine Homo sapiens 139-142 22689631-7 2012 Modelling of the SBF/RER intensities ratio has been performed assuming two single reaction rates for both fragmentation processes and computing them within the statistical RRKM formalism in the case of ortho, meta and para butyl phenols. Phenols 229-236 IK cytokine Homo sapiens 21-24
