| Additional Infomation |
Alpha-maltotriose is a maltotriose trisaccharide in which the glucose residue at the reducing end is in the pyranose ring form and has alpha configuration at the anomeric carbon atom.. It has a role as a human metabolite. Amylose is under investigation in clinical trial NCT01027325 (Resistant Starch Insulin Sensitivity Trial). Maltotriose is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Amylose is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). alpha-Maltotriose has been reported in Drosophila melanogaster, Homo sapiens, and other organisms with data available.
