Fructose

Fructose: The Fruit Sugar

Fructose, the sweetest natural sugar, is found in fruits and honey. Fructose is a monosaccharide. Fructose is also known as fruit sugar, as fructose primarily occurs naturally in many fruits. Fructose is also contained naturally in other plant-based foods such as honey, sugar cane, sugar beets, and vegetables.

Fructose, or fruit sugar, is a simple sugar found in many plants, where it is often bonded to glucose to form the disaccharide sucrose. Fructose, glucose, and galactose are the three dietary monosaccharides absorbed by the gut directly into the liver after digestion through the portal vein. The liver then converts fructose and galactose into glucose, so dissolved glucose, also known as blood sugar, is the only monosaccharide in circulating blood.
