General description
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.
Maltotriose is a (1-4)-linked glucose oligomer that serves as the inducer of the maltose regulon of Escherichia coli.
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

The jejunal absorption of glucose from (1-4)-linked glucose oligomers including maltotriose has been compared with that from free glucose and sucrose in normal subjects. A steady-state perfusion technique in vivo was used to study proximal jejunal assimilation of isotonic sugar-saline

Dendrimers provide many exciting opportunities for potential biomedical applications. However, owing to their positively charged surfaces, poly(propyleneimine) (PPI) dendrimers show toxic and haemolytic activities. One of the methods for masking the peripheral cationic groups is to modify them using carbohydrate
