Previous results from equilibrium and kinetic studies of the folding of bovine growth hormone (bGH) have demonstrated that bGH does not follow a simple two‐step folding mechanism. These results are summarized and interpreted according to the “molten globule” model. The molten globule state of bGH is characterized as a folding intermediate which largely a‐helical, retains a compact hydrodynamic radius, has packing of the aromatic side chains that is similar to the unfolded state, and possesses a solvent‐exposed hydrophobic surface along helix 106127 that readily leads association.
