Levulose, also known as Fructose, is a simple sugar found in many fruits and vegetables. It is one of the three dietary monosaccharides, along with glucose and galactose, that are absorbed directly into the bloodstream during digestion. Levulose is sweeter than glucose and is often used as a sweetener in processed foods. It is also used to make high-fructose corn syrup, which is used in many processed foods and beverages.
