Fructose.
Water is one product of every dehydration synthesis.The reason is that during this kind of reaction, one molecule (say, of glucose) loses a hydrogen atom (H) and thus makes a bond available for reaction with another molecule (say, a second glucose). This second molecule loses a hydroxyl group (-OH) to make a bond available.The two reactant molecules can now combine, and the H and -OH themselves combine to form a molecule of water. Since the overall result is effectively a loss of water from the reactants, it is called dehydration.
Carbon, hydrogen and oxygen are the only elements that make up sugars.
A disaccharide is a molecule composed of two monosaccharide units joined together by a glycosidic bond. The most common disaccharides include sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (glucose + glucose).
the molecular formula for gluose is C6H1206. This means that there are 6 carbon atoms, 12 hydrogen atoms, 6 oxygen atoms. Table sugar is made from Sucrose: C12H22O11 ---- To look at this question from a philosophical point of view, this statement challenges the axiom that you can separate something into smaller and smaller parts and still have it retain its identity. This, however, is untrue when it comes to chemistry. As you separate a sugar cube into smaller and smaller cubes, it is still sucrose. But when you are left with one molecule and you separate it, it will no longer be sucrose. Rather, it will be two molecules of glucose (through a hydrolysis reaction). You can separate these glucose molecules further but they will cease to be glucose but become another substance. Therefore, the molecule could be said to be the limit for the retention of a macroscopic object's identity.
Two monosaccharides bond together through a dehydration reaction to form a disaccharide. Water is released during this process. For example, glucose + fructose forms the disaccharide sucrose.
Monosaccharides, such as glucose, sucrose, and galactose
glucose and fructose
Sucrose molecules are the ones that make up sugar cubes, sugar granules and powdered sugar.
Effect of acid and heat on sugarSucrose (table sugar) is a disaccharide, meaning it is two simple sugars, glucose and fructose, that have reacted in such a way that they join together, losing a molecule of water in the process. A reaction that produces water is called a condensation reaction. The fructose acts like an acid, and donates a proton. The glucose acts like a base, and donates a hydroxide ion. The proton and the hydroxide ion combine to form water, and the two simple sugars combine to form sucrose.The reverse reaction, called hydrolysis, is where a water molecule is added to a molecule to break it into two parts. Hydrolysis of sucrose in water happens very slowly all by itself. But if an acid is added, it acts like a catalyst, promoting a faster reaction, but not getting used up in the process. Heating up the solution makes the reaction go even faster.The result of heating sucrose in water with a little lemon juice or vinegar in it is that much of the sucrose is converted into the two simple monosaccharides. Since fructose is a lot sweeter than sucrose, the result is a sweeter solution, even though glucose is not quite as sweet as sucrose. Since the acid is not used up, the solution is also a little tart, but that can be fixed by adding a weak base like egg whites or baking soda. If there are proteins in the solution, they can also react with the acid to neutralize it.

Carbon, hydrogen and oxygen are the only elements that make up sugars.
A disaccharide is a molecule composed of two monosaccharide units joined together by a glycosidic bond. The most common disaccharides include sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (glucose + glucose).
The molecular formula of sucrose is C12H22O11, while the molecular formula of maltose is C12H22O11. Both molecules have the same number and types of atoms (carbon, hydrogen, and oxygen), but they are arranged differently. Sucrose is a disaccharide made of glucose and fructose, while maltose is a disaccharide made of two glucose molecules.
