What are the composition and the properties of the ketohexose derived from fruit jam?

Ketohexoses are a type of monosaccharide with six carbon atoms and a ketone functional group. The most common ketohexose found in fruit jams is fructose, which is characterized by its sweet taste and high solubility in water. Fructose has a lower glycemic index compared to glucose, making it a popular choice as a sweetener. Additionally, it can contribute to the texture and preservation of fruit jams by enhancing moisture retention and stability.
