Insulin shows a complex equilibrium between monomers and hexamers, involving varying conformers and association states. We sought to perform a structural characterization of the fast-acting human insulin variant B28Asp ("aspart"). Small-angle X-ray scattering measurements reveal similar globular behavior in both the aspart and regular human insulin, with a Rg of 19Å and a Dmax of approximately 50Å, indicating similar mean quaternary assembly distribution ...
