Which of the following is true about amylopectin?

Amylopectin is a highly branched polymer of glucose and is one of the two components of starch, the other being amylose. It is characterized by its complex structure, which includes numerous branch points that allow it to be a larger molecule compared to amylose. The size of amylopectin can indeed exceed 100,000 glucose units, making it one of the largest carbohydrates in nature.

The other statements about amylopectin do not accurately reflect its characteristics. For instance, while amylopectin does have branched and unbranched chains, it is incorrect to state that it is only composed of unbranched chains. Moreover, amylopectin certainly contains glycosidic linkages, as that is how the glucose units are bonded together. Lastly, while amylopectin is found in various plant sources, it is not exclusively found in root vegetables; it is also prevalent in other plant types, particularly in grains and legumes.
