Fructose

Fructose Fructose or fruit sugar is a simple ketonic monosaccharide found in many plants where it is often bonded to glucose to form the disaccharide sucrose It is one of the three dietary monosaccharides along with glucose and galactose that are absorbed directly into blood during digestion Fructose was discovered by French chemist Augustin-Pierre Dubrunfaut in 1847
