Acid hydrolyzates of waxy-maize starch were separated to give Fractions I, II, and III [T. Watanabe, and D. French, Carbohydr. Res., 84 (1980) 115-123]. Watanabe and French suggested that Fraction II, which contains approximately 25 D-glucose residues including an alpha-D-(1----6)-linked
Amylose (average d.p. 1000) and amylodextrin (average d.p. 25) have identical 13C-n.m.r. spectra, except for some minor signals from the small amount of alpha-1----6 branch linkages present in amylodextrin. Amylodextrin can be obtained as stable solutions in much higher concentrations
The ability of amylodextrin (a linear dextrin) to act as a complexing agent or as a carrier for solid dispersion was evaluated. Blends of amylodextrin with diazepam or prednisolone were freeze-dried and kneaded at elevated temperatures, respectively. The products were
Two mechanisms are recognized for polysaccharide chain elongation: (a) the nonreducing-end, primer-dependent mechanism and (b) the reducing-end, two-site insertion mechanism. We recently demonstrated the latter mechanism for starch biosynthesis by pulsing starch granules with ADP-[14C]Glc and chasing with ADPGlc for
Iodine binding to amylodextrin fractions studied by difference spectrophotometry and potentiometry.
