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.
The Benedict's test allows us to detect the presence of reducing sugars (sugars with. a free aldehyde or ketone group). All monosaccharides are reducing sugars; they. all have a free reactive carbonyl group. Some disaccharides have exposed. carbonyl groups and are also reducing sugars. Other disaccharides such as. sucrose are non-reducing sugars and will not react with Benedict's solution. Starches are also non-reducing sugars. The copper sulfate (CuSO4) present in. Benedict's solution reacts with electrons from the aldehyde or ketone group of the. reducing sugar to form cuprous oxide (Cu2O), a red-brown precipitate.
