Abstract
Dilute solution properties of Karaya gum from Sterculia urens were studied using size-exclusion chromatography, static and dynamic light scattering and viscosity experiments in 0·1 m aq. NaCl. Solubility in water was found to be strongly dependent on the degree of acetylation. The native acetylated Karaya gum assumes a rather compact and branched conformation in aqueous solution, as evidenced by the low values of power-law exponents. In contrast, the fully deacetylated Karaya gum assumes a more expanded conformation and behaves as a random coil.
