Maltotriose is a chemical compound from the trisaccharide group . It consists of three glucose molecules linked with an α-1,4- glycoside bond.

Extraction and presentation

Maltotriose can be obtained from native starch (e.g. corn starch) by amylolysis . The resulting corn syrup, which contains, among other things, maltotriose, can be separated by chromatographic processing. The compound can also be obtained by isolating pullulan (linear fic-1,6 linked polymaltotriose) from Pullularia pullulans and subsequent enzymatic hydrolysis with pullulanase from Aerobacteraerogenes. The former reaction also takes place during starch digestion by α-amylase in saliva and the pancreas .

properties

Maltotriose is a white crystalline solid that is soluble in water. In aqueous solution, 57% of maltotriose is 4-O-α-D-glucopyranosyl- (1 → 4) 0-α-D-glucopyranosyl- (1 → 4) -β-D-glucopyranose.
