A water molecule (H2O) is produced and released. both glucose and fructose is a monosaccharide, when 2 combined together, a disaccharide is formed. this process is called condensation, and it releases an extra water molecule because the water molecule is removed. when those 2 splits up, it will use up that extra water molecule, and that process is called hydrolysis.
Disaccharides are the simple sugars that make the foundation of more composite carbohydrates. In a disaccharide the cyclic forms of two sugars are associated together by the process of condensation reaction. When a molecule of glucose and a molecule of fructose combine together they give rise to a molecule of sucrose.
In the process, a hydroxyl group from one molecule and a hydrogen atom from the other molecule gets eliminated in the form of water, with the resulting covalent bond associating the two sugars in combination at that point. Sucrose is generally termed as table sugar and is an illustration of a disaccharide.
