Microwave dielectric study on aqueous solution of glucose has revealed that the solution shows only a relaxation peak due to cooperative orientation of glucose and water molecules, accompanied with breakage and remaking of a local structure. It has been shown that the glucose molecule can be taken into the ordinary ice lattice in place of a hexagonal water cluster. On the other hand polysaccharide larger than maltotriose in aqueous solution exhibits two relaxation peaks : one observed at high frequency is due to the orientation of water molecules and the other at low frequency is due to overall rotation of the sugar molecules. The polysaccharide molecule cannot be taken into the ice lattice. It is concluded that the aqueous solution of glucose has a local structure of the ice lattice type even in the vicinity of glucose molecule. It is definite that the glucose is one of the most important materials to maintain the life of animals. The structure indicated here suggests that glucose can transport in the body more easily than other materials. In a peculiar case where humidity is low or temperature is low, the glucose plays certainly an important roll in protecting the body.
