Explain how a water molecule is produced when glucose and fructose undergo a condensation
reaction.

First, a Hydroxide atom is taken from the Glucose, and a Hydrogen from the fructose.
Then, a bond happen between Hydroxide (OH) and Hydrogen (H), creating the atom H2O, which the formula of water.

Hope this Helps :)

A condensation is a process where liquid changes into a gaseous form also known as water vapour. It occurs in the atmosphere when the temperature rises.
Water is produce when glucose and fructose undergo a condensation process. The water is removed by the combination of hydrogen and a hydroxyl together. Glucose and Fructose forms a substance called glycosidic linkage. And hydrogen and hydroxyl is separated from glucose and fructose. When Hydrogen and hydroxyl is combined, they create H2o or water.

The total number of electrons is 14
