Which carbohydrate is primarily derived from fruits?

Fructose is primarily derived from fruits and is the principal sugar found in many types of fruits. This natural sugar contributes to the sweet flavor of fruits and is easily absorbed by the body. Fructose is a simple sugar, or monosaccharide, which makes it readily accessible for energy without the need for complex digestion processes, as may be required with polysaccharides like starch.

While glucose is also found in fruits and is another important carbohydrate, fructose is specifically noted for its prevalence in many kinds of fruits. Lactose is the sugar found in milk, and maltose is a sugar that is typically formed during the digestion of starch or in the fermentation process, but neither are primarily associated with fruit. Thus, the focus on fructose highlights its unique association with fruits as a significant carbohydrate source.
