Popis:	We found abnormal light scattering from insulin particles in some aqueous solutions during the microgravity experiments, i.e. the scattering images on the monitor became coarser than those under the normal gravity, and the diffusion coefficients analyzed by the dynamic light scattering technique became smaller than those obtained under the normal one. The phenomena should be mainly due to the depression of fluctuations of small insulin particles by suppression of gravitational drifts under the microgravity. Such drifts and fluctuations of small particles give an accidental solution flow around themselves, and some imperfection of grown-up crystals would be originated by the motions of particles during pre- and post-nucleation stages. 資料番号: AA0063349003
