Glucose (aka dextrose) is the best-known simple sugar. Sugars composed of two monosaccharide units are called double sugars or disaccharides, and these are found extensively in nature. Sucrose, also known as table sugar, is the best-known double sugar. When you eat sucrose, the enzyme sucrase splits it into the simple sugars glucose and fructose, which are then quickly absorbed into the body. More complex sugars, or polysaccharides, contain links of many simple sugars. Starch, for instance, contains polysaccharides, and are therefore known as complex carbohydrates. Plant starch requires much greater digestion and hence is absorbed much more slowly than less complex sugars like sucrose or glucose. As a consequence, starchy vegetables have a medium to low Glycemic Index.
