Which type of carbohydrates is associated with long chains of glucose?

The answer identifies starches as the type of carbohydrates associated with long chains of glucose. Starches are polysaccharides, which means they are made up of many glucose units linked together in long chains. This structure allows starches to serve as a significant storage form of energy in plants. When consumed, digestive enzymes break down starches into glucose, which can then be utilized by the body for energy.

In contrast, sugars, simple carbohydrates, and fibers do not possess the same structure as starches. Sugars and simple carbohydrates consist mainly of single or double sugar units (monosaccharides or disaccharides), which do not form the long chains characteristic of starches. While fibers can also be complex carbohydrates, they are primarily composed of non-starch polysaccharides that may not be digestible by humans and provide health benefits in different ways, such as promoting digestive health. Thus, the unique characteristic of starches being long chains of glucose makes them the correct choice in this context.
