The natural substrate for the enzyme cellobiase is cellobiose. This is a disaccharide composed of two beta glucose molecules. However, when scientists study enzyme function, it is best if there is an easy way to detect either the amount of substrate that is used up or the amount of product that is formed.
In general, disaccharides and polysaccharides contain both reducing and nonreducing sugars. These carbohydrates are represented and their formulas are written from nonreducing end to reducing end. A common disaccharide is lactose, which is found only in milk. Lactose is formed from monosaccharides Î² -D- galactose and Î² -D- glucose . The anomeric carbon of the Î² -D-galactose molecule reacts with the C-4 hydroxyl group of the Î² -D-glucose molecule to form the glycosidic bond (see Figure 1).
