Fructose

A natural byproduct of fruit and honey, this sweet substance is available in granulated and liquid forms. It is more water soluble than glucose, sweeter than glucose, and twice as sweet as sucrose, yet when heated, fructose loses some of its sweetening flavor. Fructose is a classified as a simple sugar because it is composed of only half of the sucrose molecule. It should not be substituted for regular sugar in recipes. Because of its makeup and the way it is digested by the body, it is an acceptable sweetener for diabetics. Also referred to as fruit sugar and levulose.
