WebEnzymes are life’s great facilitators. They create the conditions needed for biochemical reactions to happen fast. The general name that chemists use for a chemical entity that increases the speed of a reaction is a “catalyst.” Enzymes are biological catalysts--they catalyze the chemical reactions that happen inside living things. WebReactions catalyzed by enzymes are among the most effective, selective, and 'green' processes available today. The advantages of using biocatalysts include their high degree of regio- and stereo-specificity, versatility, and high reaction rates under mild reaction conditions. Enzyme catalyzed enantioselective C-C bond formation reactions are ...
