However, "sugar" is a term that is given to a whole range of compounds of a certain general structure that display sweetness as a physical property.

Sucrose is a disaccharide, which means that its structure is composed of two sugar units - in this case one unit of glucose and one unit of fructose. Sucrose can be obtained from sugar cane (approx 20% by weight) or sugar beets (15% by weight).
