A novel global hydrodynamic analysis of the molecular flexibility of the dietary fibre polysaccharide konjac glucomannan

Abstract

procedure an estimate of (13 ± 1) nm is found for L p and a value of (330 ± 10) g mol

On hydrodynamic methods for the analysis of the sizes and shapes of polysaccharides in dilute solution: A short review

“…This is ably demonstrated by the different persistence lengths calculated by the Burchard-Stockmayer-Fixman, Hearst, Bushin-Bohdanecky and Yamakawa-Fujii approaches (Kök, et al, 2009): realiance on a single measurement is unwise. The persistence length and mass per unit length can be estimated using, Multi-HYDFIT program (Ortega and García de la Torre, 2007) which considers data sets of hydrodynamic parameters for different molecular weights.…”

Chitosan and its hydrophobic derivatives: Preparation and aggregation in dilute aqueous solutions

“…It was shown [31,141] that an increase in the chain length of hydrophobically modified chitosan entails a decline in the CAC, that is, promotes aggre gation. At the same time, in [128], the inverse effect was observed: The value of the CAC increased with the molecular mass of the hydrophobically modified chi tosan.…”

The mechanism of sodium hydroxide solution promoting the gelation of Konjac glucomannan (KGM)

“…The intrinsic viscosity was determined by the experimental values of Newtonian viscosity in dilute solution, the relationships were as follows (Kök, Abdelhameed, Ang, Morris, & Harding, 2009;Kwaambwa, Goodwin, Hughes, & Reynolds, 2007).…”

“…As is shown in Fig. 1 (Kök, Abdelhameed, Ang, Morris, & Harding, 2009), KGM is mainly composed of D-mannose and D-glucose units through b-1,4-linkages in a mole ratio of 1.6:1, with a low degree of acetyl groups (Cescutti, Campa, Delben, & Rizzo, 2002;Dave, Sheth, McCarthy, Ratto, & Kaplan, 1998;Yeh, Lin, & Chen, 2010). It has been widely used in green food and healthcare for its unique pharmacological functions.…”
