Abstract
The molecular motion of sucrose in water/alcohol/sucrose/casein soluti ons was studied by C-13-NMR spin-lattice relaxation measurements. The results suggest that the conformation of sucrose is unaffected by conc entration, temperature, or the presence of alcohol or casein. There is no evidence for the interaction of sucrose with either alcohol or pro tein. Changes in the hydrodynamic radius of sucrose from relaxation me asurement using solution or water viscosities were inconclusive.
