説明
Conformational behavior of curdlan, a (1→3)-β-D-glucan, in its trisodium phosphate (Na3PO4) aqueous solution which was utilized as a food additive was examined. In the concentration range of 0.05 to 0.4 M where curdlan could be dissolved, it was found that the viscosity of curdlan solution was decreased a little with the increase of the alkaline concentration, that the absorption maximum (λmax) of visible absorption spectra of a congo red solution showed a red shift from 485-490 to 518-520 nm by the addition of curdlan, and that a circular dichroism (CD) band was observed. When 1 M NaOH solution of curdlan was added to the curdlan 0.4 M Na3PO4 solution a drastic decreasing of viscosity, blue shift of curdlan-congo red solution, and no CD band were observed. These results suggested that curdlan took up an ordered conformation in the Na3PO4 solution, but, by the addition of the NaOH solution a conformational transition occurred to a random coil which is similar transformation having been observed in the NaOH solution.
