Abstract
Small-angle neutron and X-ray scattering have become invaluable tools for probing the nanos- tructure of molecules in solution. It was recently shown that the definite integral of the scattering profile exhibits a scaling (power-law) behavior with respect to molecular mass. We derive the origin of this relationship. While the behavior does not follow a single scaling law over all molecular sizes, we discuss how an apparent scaling relationship can be used to identify differing levels of disorder over `local¿ {approximatelay less than}30 A distances. We apply our analysis to globular and intrinsically disordered proteins.Citation
