For the clarification and enhancement of function of biological molecules with nm size, we believe that small-angle neutron scattering measurement in wide- range giving structural information of the molecules with atomic resolution is important. We have thus designed the high-intensity small-angle neutron scattering instrument HI-SANS for the J-PARC in order to carry out the efficient measurement in wide- range including high-q range of 1100 nm. In order to use effectively the information on the structure over wide- rang, we have performed the simulation of neutron scattering function from typical proteins in solution using Debye formula. The result showed that change of the scattering function from = 0.1 to 5 is important for the new structural analysis which added the information on an internal structure.
