Amylopectin

Amylopectin forms a branched structure with about 30 glucose units in a chain among branches. There are usually slightly more  'outer' unbranched chains (called A-chains) than 'inner' branched chains (called B-chains) as indicated in figure. There is only one chain (called the C-chain) containing the single reducing group.

 5As indicated earlier, each amylopectin molecule contains up to two million glucose residues in a compact structure. The branched structure of the amylopectin makes the molecule somewhat striped in appearance, with the knotted  branch points all in a row, and the smooth chains separating them. These molecules are so large that this stripped appearance shows up under the  light microscope, forming what appears to be "growth rings" in the starch grain as can be seen in figure.
