Table sugar is commonly used to sweeten food. There are different kinds of sugars, including glucose, fructose, and sucrose. Glucose is commonly called blood sugar; fructose is sugar in fruit; sucrose is table sugar.
Sucrose is a carbohydrate, which is a chemical made of carbon, hydrogen and oxygen.
Sucrose molecules contain 12 atoms of carbon, 22 atoms of hydrogen, and 11 atoms of oxygen (C12H22O11).
Sucrose is produced by plants in a process called photosynthesis. Some plants, such as sugar beets and sugarcane, produce so much sucrose that they are sugar crops (plants grown to extract sugar that is sold).
Crystals are orderly arrangements of particles that make up a substance. For sucrose, the building blocks are molecules. As these molecules stack together, the structure formed is cubic in shape.
Use a magnifying lens to study dry table sugar. Spread the sugar crystals and look for small cubes. This is the shape of crystals of sucrose.
