A catalyst — whether chemical or biological — acts by increasing the velocity of reactions. We will now examine the kinetics of enzymatic reactions. The velocity of an enzymatic reaction is generally followed up by measuring the quantity of substrate transformed per unit time; one can also record the quantity of the product (or one of the products) formed by [...]
In this article we will discuss about the classification of enzymes. Some enzymes are often designated by common names based on usage (pepsin, trypsin, chymotrypsin, papain etc); but these names contain no information on the substrate and the reaction catalyzed. In certain cases, enzymes catalyzing hydrolysis reactions are designated by the name of the substrate followed by the suffix "ase" [...]
In this article we will discuss about the structure of enzymes. This will also help you to draw the structure and diagram of enzymes. Enzymes are proteins, having primary, secondary, tertiary and in certain cases, even quaternary structures. Sometimes, this protein part (or apoenzyme) is not sufficient for catalytic action which then requires the presence of a co-factor. I. Polypeptide [...]
