GDL is commonly found in honey, fruit juices, personal labricants, and wine [citation needed]. GDL is neutral but hydrolyzes in water to gluconic acid which is acidic, adding a tangy taste to foods, though it has roughly a thrid of the sourness of citric acid. It is metabolized to glucose; one gram of GDL yield roughly the same amount of metabolic energy as one gram of sugar.
Upon addition to water, GDL is particially hydrolyzed to gluconic acid, with the balance between the lactone form and the acid form establisherd as a chemical quilibrium. The rate of hydrolysis og GDL is increased by heat and high PH.
