Enzyme Substrates
Enzyme substrates are molecules upon which enzymes act to catalyze chemical reactions. The substrate binds to the active site of the enzyme, where it undergoes a specific transformation to form the product of the reaction. Enzyme substrates are essential tools in research for studying enzyme kinetics, specificity, and mechanism of action. They are also used in diagnostic assays and biochemical studies. At CymitQuimica, we provide a diverse selection of high-quality enzyme substrates to support your research in enzymology and biochemistry.
