Fructose is indeed a monosaccharide and is often referred to as ""fruit sugar"" due to its natural occurrence in many fruits, as well as in honey, sugar beets, sugar cane, and certain vegetables.
Its sweetness makes it particularly appealing in food and beverage applications, being 1.2 to 1.8 times sweeter than sucrose. Since fructose metabolism doesn't require insulin, it has a low impact on blood glucose levels, making it an option for people managing their blood sugar.
