General description

α-1,4-glucan with α-1,6-cross-linking; one terminal group per 25 glucose units

Application

Amylopectin is a glucose-based, highly-branched polysaccharide which together with amylose makes starch. The glucosidic bonds of amylopectin are α-1,4 in the glucan chain and α-1,6 at the branch points. Amylopectin from maize differs in structure form amylopectin from other plant species and is used in the study of the development of starches.

The compatibilities of amylose/tea polysaccharide (Am/TPS) and amylopectin/tea polysaccharide (Ap/TPS) in water were investigated with theoretical calculations and experimental measurements. To achieve this, dilute-solution viscometry (DSV) and high-speed differential scanning calorimetry (hyper-DSC) were used. The compatibility criteria on the basis
