Solution Conformation of Konjac Glucomannan Single Helix

The possibility of the existence of konjac glucomannan (KGM) single helix in dilute solution was discussed finely by ultraviolet-visible spectrophotometer (UV-Vis) with Congo red complex, viscosimetry and circular dichroism (CD). KGM bound to Congo red and the λ max characteristic shifted markedly to longer wavelength (514 nm) in 0.25 M aq NaOH. The shifts of λ max and intrinsic viscosity were also compared in different mediums, such as...
