Fructose (fruit sugar) and glucose (grape sugar) are monosaccharides – single sugar molecules. HFCS (High Fructose Corn Syrup) contains fructose and glucose. It is widely used as a sweetener in processed foods and drinks.
When fructose and glucose are combined, they form a disaccharide – double sugar molecule – known as sucrose (common table sugar). Hence, fructose is a natural component of sucrose. Both fructose and sucrose are found in fruit.
Like HFCS, Sucrose is used as a sweetener in processed foods and drinks.
