Interference solute sugar molecule

However, the pattern is complicated by several factors. The sugar molecules to be hydrogenated mutarotate in aqueous solutions thus coexisting as acyclic aldehydes and ketoses and as cyclic pyranoses and furanoses and reaction kinetics are complicated and involve side reactions, such as isomerization, hydrolysis, and oxidative dehydrogenation reactions. Moreover, catalysts deactivate and external and internal mass transfer limitations interfere with the kinetics, particularly under industrial circumstances. 

If, however, it is put in water, solvent molecules penetrate the fine Assures and cracks of the crystal surface, interact with the hydroxyl groups of the glucose or fructose residues and thereby interfere with the cohesion of the crystal to such an extent that the average kinetic energy is sufficient to detach the individual C12H22O11 molecules from the solid phase and drive them into the liquid. There, combined with a few water molecules, they execute molecular motion under the influence of random impacts, which push them hither and thither and make them victims of chance. In a short time the solid sugar crystal disappears with the automatic formation of a homogenous solution.
