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.
The site on an enzyme that binds the substrate (known simply as the substrate binding site) is most often a pocket or cleft in the approximately globular structure of the enzyme. The term substrate has another meaning in chemistry. Some chemical syntheses are carried out in mixed phases; for example, the reactants exist in solution but the reaction itself occurs at the surface of a solid.
