Enzymes act as a biocatalyst that particularly catalyzed the reactions in the living organism by them to carry out the reaction. Enzymes have application in food, detergent, pharmaceutical and paper industries. Nowadays, the enzymatic hydrolysis and enzyme-based processes are preferred to the chemical ones due to the environmentally friendly nature, efficient process control, high yield, low refining costs and process safety. There are many enzymes that are used in different industries for the production of chemicals, drugs as well as other pharmaceutical products. Synthesis of enzymes can be carried out in different ways such as organic as well as inorganic synthesis but it depends upon on the nature of chemicals and reagents used for their synthesis both in laboratory and industrial level. Xylan is the major compounds found in the inner part of hemicullulose to make the cell of plants thicker as compares to the other cells. Ligninase as one of the important industrial based enzyme used to control the pollution in the environment. This enzyme has biotechnological applications in the fields of agricultural sciences for the production of agricultural products. Lipase is one enzyme that is used in fat metabolism for catalysis the fat molecules. It has also other activities other than digestion such as transportation of lipids in the form of triglycerides.
