What is the difference between glucose, fructose and lactose?
Glucose and Fructose are monosaccarides and are Isomers of the same chemical formula: C6,H12,O6 the difference between the molecules is the two is the placement of two bonds. Fructose must be converted into glucose before it can be used by the body. Glucose does not need to be digested before it can be used. Lactose is a disaccharide (made up of 2 monosaccarides) Lactose is formed when Glucose and Galactose join together in a reaction called dehydration synthesis. Basically yes, fructose and lactose are converted to glucose to be absorbed into the bloodstream.
