Binding of hexadecyltrimethylammonium bromide to starch polysaccharides. Part II. Calorimetric study
Isothermal titration calorimetry was used to study the interaction between hexadecyltrimethylammonium bromide, CTAB, and three starch polysaccharides, amylose from potato, amylopectin from potato and amylopectin from barley. The enthalpy change for consecutive additions of CTAB to starch polysaccharide solutions were measured at 27degreesC. The starch-CTAB interaction enthalpies, DeltaH(f), were c
