General description

Maltotriose is an oligosaccharide with α-1,4 glycoside linkage. It does not possess any ionic groups, hence is suitable for examining the interaction between molecular motion and water molecules.

Application

Maltotriaose hydrate can be used:
  • for sensitive analysis of simple sugars
  • to study heat capacities for sugars and sugar alcohols in dilute aqueous solution by calorimetry
  • as an internal standard in the analysis of sugar levels, during fermentation process in wort samples using HPLC and spectrophotometry
