Starch is the second most abundant biopolymer after cellulose. It is synthesised by plants, stored in organs such as seeds and tubers, and subsequently used as an energy source during germination and growth. Starch is stored in distinct granules, the carbohydrates in these granules comprising two polydisperse polymers, amylose and amylopectin. Both of these polymers are composed of α-D-glucopyranose subunits. Amylose is an essentially linear polymer with the subunits being connected by α-(1→→4)-linkages. Amylopectin is a highly branched polymer in which the subunits are connected by α-(1→4)-linkages, and the branches are attached to the linear chains by α-(1→6)-linkages.
