Compare and contrast the three groups of carbohydrates: monosaccharides, disaccharides, and polysaccharides
Monosaccharides (glucose, fructose, and galactose) are the simplest forms (simple sugars) of carbohydrate. They require no digestion and are absorbed directly into the bloodstream from the small intestine. Disaccharides (lactose, maltose, and sucrose) are pairs of simple sugars. They must be converted to simple sugars before they can be absorbed. Polysaccharides (starch, glycogen, and fiber) are complex carbohydrates. They are found in plants and vegetables. These are very difficult to break down, and some fiber cannot be broken down.
