Fructose is a natural, simple carbohydrate (monosaccharide) found in many fruits and made commercially by the enzymatic conversion of dextrose (see Dextrose) derived from corn (Zea mays). Also known as fruit sugar, fructose is the sweetest among all naturally occurring sugars and serves as a natural sweetener. Fructose is a low glycemic sweetener, meaning that it does not increase blood sugar as much as glucose or starch after consumption.1-3
