ENZYMES
Definition:
Enzymes are the most important group of proteins that are produced by the living organisms that acts as a catalyst to bring about a specific biochemical reaction. Composition:
Enzymes are composed of hundreds of amino-acids joined together and coiled upon them-selves to form a globular structure. The catalytic activity is restricted to small area known as active site. Some enzymes consist solely of proteins, while other has a non-protein part known as cofactor. The detachable cofactor is known as activator. If the non-protein part is covalently bonded it is known as prosthetic group but if it is loosely attached it is known as coenzyme. Characteristics of Enzymes:

* All enzymes are globular proteins.
* They increase the rate of chemical reaction without themselves being used up. * There presence does not affect the nature or the properties of end products. * They are specific in action.

* They lower the activation energy of reactions.
Function:
Enzymes are important proteins that catalyze the chemical reactions. In enzymatic reactions, the molecules at the beginning of the process on which the enzyme attack are called substrates, and the enzyme converts them into different molecules, called the products. Discovery:

The discovery of enzymes is an important achievement. Many scientists contributed in the...
