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
