A sugar is defined by the Oxford English Dictionary as, "Any of the class of soluble, crystalline, typically sweet-tasting carbohydrates found in living tissues and exemplified by glucose and sucrose." There are many types of sugars, which are categorized into two classes:monosaccharides (1 sugar unit) and disaccaharides (2 sugar units). Table sugar is a disaccharide.

The three monosaccharide sugars are glucose, fructose, and galactose. Glucose is found in carbohydrates such as wheat flour and starch. Fructose is found in fruits and vegetables. Galactose is found in some milk, gums, artificial jellies, and artificial beverage flavoring. The chemical formula for monosaccharides is C6H12O6.

Disaccharide sugars are formed through a combination of two monosaccharide molecules to form lactose, sucrose, andmaltose. Lactose (glucose+galactose) is found in milk. Sucrose (glucose+fructose) is found in sugar cane and byproducts of cane sugar including table sugar. Maltose (glucose+glucose) is not commonly found in food, but can be formed during the digestive process. The chemical formula for disaccharides is C12H22011.

What is the chemical formula for sucrose?

The chemical formula of a compound indicates the number and type of atoms present in the compound. 

The chemical formula for sucrose is `~C_12H_22O_11` .

The letters in the formula are the symbols for each element present in the compound. The symbol for each element can be found in the periodic table.

  • C is the element symbol for carbon
  • H is the element symbol for hydrogen
  • O is the element symbol for oxygen

The subscripts in the formula indicate how many atoms of each element are present in the compound.

  • There are 12 carbon (C) atoms, 22 hydrogen (H) atoms, and 11 oxygen (O) atoms.

The carbon, hydrogen, and oxygen atoms are held together in the compound by covalent bonds. In a covalent bond, the electrons in the bond are shared between atoms.

Notice that sucrose has a very similar chemical formula to other sugar compounds such as glucose: `~C_6H_12O_6` .
