NettetWe have been able to characterize the crystal unit cells of crystalline insulin in native granule preparations and show that the shape and dimensions are in accordance with the size of some insulin hexamers determined from crystals of this hormone prepared in vitro. 2. Results and discussion Nettetessential to their existence (2). Insulin crystallization is an example where fine-tuning of the kinetics of growth of the new phase may be crucial for the biological function of the crystals. Aside from crystalline biominerals (2), insulin is a unique example of be-nign crystallization in vivo with important biological function (3-5);
