Enzymes for Life Science Research - Alfa Aesar

Enzymes are proteins that catalyze biochemical reactions. Typically they are highly selective catalysts acting only on specific substrates. Enzymatic activity can affect any number of biological processes. They play important roles in cell cycle regulation and also in metabolism.

Enzymes frequently require organic and inorganic cofactors to assist in catalysis. Like all catalysts, enzymes increase the rate of a reaction by lowering the activation energy. Enzymes, like chemical catalysts, are not consumed by the reactions they catalyze, nor do they alter the equilibrium of these reactions. Most enzyme reaction rates are millions of times faster than those of comparable un-catalyzed reactions and some are so fast that they are diffusion limited.

Alfa Aesar provides many frequently used enzymes to assist your life science research needs.
