D-Fructose, or fruit sugar, is a simple monosaccharide found in many plants. It is the sweetest of all sugars. It is found in honey, corn syrup, and in the fruit and other parts of plants. It is much sweeter than sucrose (cane sugar). It is a ketohexose and is often bonded to glucose to form the disaccharide sucrose. It is one of the three dietary monosaccharides, along with glucose and galactose which are absorbed directly into the bloodstream during digestion.
It is a Ketohexose and has only 3 chiral centers, so 23 diastereoisomers
