Amylopectin is a highly branched polysaccharide and the major component of starch (typically 70-85% in most starches). It consists of α-D-glucopyranose units primarily linked by α-1,4-glycosidic bonds in linear chains with α-1,6-glycosidic branch points occurring every 24-30 residues. This branching creates a compact, tree-like structure enabling rapid enzymatic hydrolysis and gel formation upon heating in water. Amylopectin contributes to the viscosity, texture, and retrogradation properties of starch-based foods. It is biosynthesized in plants via starch synthase and branching enzymes and is widely used in food, pharmaceuticals, and industrial applications as a thickener and stabilizer. Unlike amylose, its branched architecture prevents extensive crystallization, leading to softer gels.
