Abstract: Partial α-amylolysis of wheat starch (I)  and chromatog. sepn. of the formed saccharide mixt. afforded macrodextrins (II) which were characterized by mol. wt., periodate oxidn., and α- and β-amylolysis and their structure and the branching d. compared with those of I from potato I. Wheat II contained an av. 3-5 internal chains 6.0-8.5 glucose units long. The structure and yield of II pointed to the irregularity and heterogeneity of branching of native amylopectin. II were not formed from maize I which provided evidence for the more regularly branched amylopectin in maize.
