General description

Maltotriose is a (1-4)-linked glucose oligomer that serves as the inducer of the maltose regulon of Escherichia coli.
Maltotriose, a short-chain glucose-based oligosaccharide elicits a sweet taste. This trisaccharide is made up of three 1,4 linked α-D-glucose units.

Application

Maltotriose has been used:
  • as a carbohydrate standard to determine the carbohydrate composition of the wort by high-performance liquid chromatography paired with refractive index detection (HPLC-RID)
  • as an acceptor substrate to determine the transglycosylation activity of amylomaltase
  • as an acceptor substrate in hydrolytic activity and thermal stability assays
  • in a comparative study to investigate the infrared (IR)-Fourier spectra of a carbohydrate series

Maltotriose has been used:
  • in a study to assess the rapid determination of the attenuation limit of beer
  • in a study to investigate the influence of fourth-generation poly(propyleneimine) dendrimers on blood cells

Biochem/physiol Actions

Maltotriose is a ligand of the human sweet taste receptor hT1R2/hT1R3.

Although sweet-tasting saccharides possess similar molecular structures, their relative sweetness often varies to a considerable degree. Current understanding of saccharide structure/sweetness interrelationships is limited. Understanding how certain structural features of saccharides and/or saccharide analogs correlate to their relative sweetness can
