In aqueous solutions, there are three forms of glucose: the cyclic alpha-form (36%), the cyclic beta-form (64%), and a trace amount of the open-chain form. At equilibrium, the cyclic alpha- and beta-forms are constantly interchanging when in solution. 2. Name the monosaccharides and disaccharides in amylose and cellulose. Compare the structural and conformation differences between amylose and cellulose. A simple iodine test can be used to distinguish the two polysaccharides.
