Amylose, a putative linear alpha-(1-->4)-glucan and a component of most starches, was isolated from potato, rice, and wheat starches by forming the 1-butanol complex in a solution of the starches. It previously had been found that these amyloses were incompletely

In this study, we investigated which enzymes are involved in debranching amylopectin during transient starch degradation. Previous studies identified two debranching enzymes, isoamylase 3 (ISA3) and limit dextrinase (LDA), involved in this process. However, plants lacking both enzymes still degrade

Instrumental and procedural optimizations are developed for a new method to obtain 2-dimensional distributions for branched homopolymers based on size and branching. The method uses 2-dimensional off-line size-exclusion chromatography (SEC) and chemical debranching, in this case using debranching enzymes on
