2. What is the use of enzymes in medicine? Enzymes are the preferred markers in various disease states such as myocardial infarction, jaundice, pancreatitis, cancer, neurodegenerative disorders, etc. They provide insight into the disease process by diagnosis, prognosis and assessment of response therapy. Enzymes can also be used for analytical tests & drug manufacturing. They also work as therapeutic enzymes (like replacement).

3. USES OF ENZYMES :- ANALYTICAL TESTS : Diabetics use strips of paper impregnated with glucose oxidase to monitor their blood sugar. The presence of enzymes where they should not be present can also help to diagnose disease. For example when the liver is diseased or damaged, enzymes leak into the bloodstream. Testing the blood for these enzymes can confirm liver damage. THERAPEUTIC ENZYMES : Enzymes are sometimes used as medicines to replace enzyme deficiencies in patients like is the use of blood clotting factors to treat haemoplilia , or the opposite where proteases are used to degrade fibrin; to prevent the formation of dangerous blood clots. Nuclease is a possible therapy for cystic fibrosis, but it is not clear how commercialized and therapeutically successful this has been. Proteases are used to clean wounds and therefore accelerate the healing process. DRUG MANUFACTURE : The chemical synthesis of complex drugs is often difficult and companies turn to enzymes to perform chemical conversions In a semi-therapeutic way; Enzymes are used to aid digestion, to supplement the natural amylase, lipase and protease produced by the pancreas. People with lactose intolerance lose the enzyme lactase. Lactase supplements help to avoid stomach upsets for these people.

4. USES OF ENZYMES WITH EXAMPLES :- Enzymes can be used for Aiding Digestion. Example: Amylases, Proteases and Lipase. They can also be used as Deworming agents. Example: Papain. Enzymes act as anti-clotting agents like Fibrinolytic and Thrombolytic. Examples: Urokinase and Streptokinase. Enzymes can be used as surface disinfectants. Example: Trypsin. They can also be used in the diagnosis purpose. Example: Glucose oxidase along with peroxidase to detect the level of glucose (colorimetric estimation). Liver disease: SGPT, SGOT Heart attacks (MI): SGOT Myocardial Infarction: Creatine phosphokinase.
