Catalysis and Enzymatic Reactions
Catalysis is the kind of chemical reaction in which the rate (speed) of a reaction is enhanced by the catalyst which is not consumed during the process of reaction and afterward it is removed when the catalyst is not used to make up the impurity in the product. The enzymatic reaction is the reaction that is catalyzed via enzymes.
Lock And Key Model
The lock-and-key model is used to describe the catalytic enzyme activity, based on the interaction between enzyme and substrate. This model considers the lock as an enzyme and the key as a substrate to explain this model. The concept of how a unique distinct key only can have the access to open a particular lock resembles how the specific substrate can only fit into the particular active site of the enzyme. This is significant in understanding the intermolecular interaction between proteins and plays a vital role in drug interaction.

This stereospecific synthesis, starting with enantiometrically pure (R)-malic acid, yields a bromoepoxide.
Write out the complete synthesis on a separate sheet of paper, and then draw the structure of the product of step 5.
• Use the wedge/hash bond tools to indicate stereochemistry where it exists.
• If the reaction produces a racemic mixture, draw both stereoisomers.
• Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner.
• Separate multiple products using the + sign from the drop-down menu.
