This is a short slide for understanding the definition , properties and function of enzyme

1. Ladies And Gentlemen

2. Enzymes
*Definition
*Properties
*Function

3. Catalyst
Substance that increase the
velocity of a reaction.
Do not undergo any change.

4. Enzyme
Soluble colloid organic catalyst
Protein in nature except some
RNA catalytic enzymes
Accelerate the reaction
 Have the specificity

5. According to Summer and
Myrback –
Enzymes are simple or
combined proteins acting as
specific catalyst

6. Properties
Protein in nature (except some
catalytic RNA enzymes )
Fast a reaction 107 times more
 High specificity
 Act in optimum at pH(4-5)
and temperature at (35-40°C)

7. Sometimes needs inorganic and
organic compounds for action
Have a life of several weeks or
month then get broken down or
replaced by new

8. Do not alter the equibrillium

9. Function
Used for various purposes
Ex- Renin for cheese making
- Papain for meet cooking
- Penicillin synthetase for
penicillin production

12. Used for disease diagnosis
Ex-* AST(Aspertate Aminotransferase)
/SGOT(Serum glutamic oxaloacetic
transaminase )
Liver disease Myocardial infarction

13. *ALT(Alanine
Aminotransferase)/SGPT(serum
glutamic pyruvic transaminase )
Liver disease Kidney disease

14. *Lipase increased
Pancreatic tumor Stomach
& cholecystitis problems

17. *Alkaline phosphatase increased
Rickets Hyperparathy
roidism
Osteoblastic
carcinoma
Obstructive
jaundice

18. *Acetylcholine esterase increased
Nephrotic syndrome
*Lactate dehydrogenase increased
Tissue damage and organ failure
*Creatine kinase increased
Heart attack
Muscle injury
Strenuous exercise
Drinking too much alcohol
Taking certain medicine and supplement

19.  Treatment of certain diseases
Ex-
*Streptokinase
Myocardial infarction
Pulmonary embolism
Arterial thromboembolism
*Urokinase (clot busting )
Blood clot in the lung
