Starches from five underutilized tubers (canna, potato, Chinese yam, water chestnut, and taro) were extracted to investigate quantitative structure-property relationships (QSPR) in each starch using a combination of X-ray diffraction (XRD) and small-angle X-ray scattering (SAXS). Structural parameters of the

The action patterns of glucoamylase (amyloglucosidase) and glucosyltransferase (transglucosylase) on D-[1-14C]glucose, [1-14C]maltose, and [1-14C]malto-oligosaccharides (labeled at position 1 of the D-glucose group at the reducing end) have been investigated by paper-chromatographic and oligosaccharide-mapping techniques. Under the conditions of the experiments

Beta-glucosidase was purified from a crude cellulase preparation from Aspergillus niger by affinity chromatography on a methacrylamide-N-methylene-bis-methacrylamide copolymer bearing cellobiamine. The purified enzyme was a dimer with an isoelectric point of 4.0. The molecular mass of the enzyme was estimated
