What is sugar?

Sugar is a carbohydrate that is found naturally in all green plants and in every fruit and vegetable. It is the major product of photosynthesis, the process by which plants use the sun's energy to convert carbon dioxide and water into food. Sugar occurs in greatest quantities in sugar cane and sugar beets. These two plants are the commercial sources of sugar.

Sugars can be sacharides, or disacharides (a combination of two sacharides).
