is sucrose composed of glucose and fructose?
<answer> Yes <context> Sucrose. Sucrose is made from glucose and fructose units: Sucrose or table sugar is obtained from sugar cane or sugar beets. The glucose and fructose units are joined by an acetal oxygen bridge in the alpha-1 on the glucose and beta-2 on the fructose orientation. The structure is easy to recognize because it contains the six member ring of glucose and the five member ring of fructose.
