Amylopectin

Amylopectin is a glucose polymer that is part of the mixture that makes up starch.

Amylose is a glucose polymer. At the top of the image is a chain of circles joined together with chains that branch off the initial chain to show the branched polymer chain. Below that is the structure of glucose polymer, which shows how the glucose monomers can join together using 1, 4, glycosidic bonds, and branches off the chain can form using 1, 6, glycosidic bonds. The 6-membered ring form of glucose is made of carbons 1 to 5, with oxygen between carbon 1 and carbon 5. The OH groups at carbons 2 and 4 point down. The O H group at carbon 3, and the C H 2 O H group at carbon 5, point up.

Figure 1: Amylopectin is composed of branched chains of glucose monomers connected by α 1,4 and α 1,6 glycosidic bonds. Glycogen (not shown) is similar in structure to amylopectin but more highly branched.
