Monosaccharides, such as glucose (also known as dextrose), fructose, and galactose, are the only sugars that can be absorbed directly from the gastrointestinal tract into the blood. Disaccharides, such as sucrose (common table sugar), lactose, and maltose, are the most common sugars in foods but must be metabolized to monosaccharides before being absorbed into the bloodstream. |
