Final answer:
Amylopectin, a branched-chain polysaccharide, forms glycosidic linkages between the first and fourth carbon atoms of different glucose monomers.
Step-by-step explanation:
Amylopectin, a branched-chain polysaccharide, forms glycosidic linkages between the first and fourth carbon atoms of different glucose monomers, resulting in a helical structure. The branches in amylopectin are connected to the main chain by a 1,6-glycosidic linkage. This branching structure makes amylopectin more accessible to water for hydrogen bonding and easier to digest.
