Abstract:
This paper presents optical and chirooptical data on the interaction of the microscopy-staining agent ruthenium red with carboxylated polysaccharides in dilute aqueous solution. The polysaccharides used are both natural (alginate and pectate) and semisynthetic (C6-oxidized cellulose and C6-oxidized amylose). A preliminary discussion of the molecular structure and conformational features which control the interaction is presented.
