ENZYMOLOGY
,ENZYMES
Enzymes are biocatalysts – synthesized
living cells.
They are defined as the substance tha
increases the velocity or rate of a chem
reaction without itself undergoing any
change in the overall process .
,CHEMICAL NATURE AND PROPERTIES O
ENZYMES
The functional unit of enzyme is Holoenzyme.
Holoenzyme = Apoenzyme + Coenzyme
Apoenzyme is the protein part and coenzyme is the no
part.
Enzymes are:
1. Protein in nature
2. Colloidal
3. Thermolabile
4. Specific in their action
, CLASSIFICATION OF ENZYMES
CLASS 1: OXIDOREDUCTASE
This group of enzymes will catalyze oxidation of one subs
simultaneous reduction of other substrate.
Eg: Pyruvate LDH Lactate
NADH+H NAD+
CLASS 2: TRANFERASES
This class of enzymes transfers one group from one substrate to
Substrate.
Eg: Glucose HEXOKINASE Glucose-6-phosphate
Mg
ATP ADP
