what would the substrate be in a disaccharide reaction
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.
Biochemistry [edit]. In biochemistry, the substrate is a molecule upon which an enzyme acts. Enzymes catalyze chemical reactions involving the substrate(s). In the case of a single substrate, the substrate bonds with the enzyme active site, and an enzyme-substrate complex is formed.n chemistry, a substrate is typically the chemical species being observed in a chemical reaction, which reacts with reagent to generate a product.
