Which of the following is NOT an example of a simple sugar?

Starch is not considered a simple sugar; it is classified as a complex carbohydrate. Simple sugars, also known as monosaccharides and disaccharides, are the most basic forms of carbohydrates. Monosaccharides include single sugar units like glucose and fructose, while disaccharides consist of two sugar units, such as lactose (glucose + galactose) and maltose (glucose + glucose).

In contrast, starch is composed of many glucose units linked together in long chains and serves as the storage form of energy in plants. Due to this structure, starch is digested more slowly and provides a more sustained source of energy compared to simple sugars, which are quickly absorbed into the bloodstream. Understanding these differences is crucial in both nutritional contexts and food preparation, as they impact flavor, sweetness, and the body's energy levels.
