Classification of Enzymes

Enzymes are classified into six major groups on the basis of the type of the reaction they catalyze.

These are

1. Oxidoreductases

2. Transferases

3. Hydrolases

4. Lyases

5. Isomerases

6. Ligases (synthases)

Key - Just Imagine that there is an electron ē, which get transferred to the molecule of water(H₂O). This molecule get break and form its Isomer. After some time it again synthesized into Water(H₂O).

Collect information from bold words

electron ē Oxidoreductases (Transfer of electrons)

transferred Transferases (Transfer of functional group)

water(H₂O) Hydrolases (Hydrolysis reaction)

break Lyases (Cleavage of C-C, C-O, C-N and other bonds)

Isomer Isomerases (Transfer of Groups within a molecule)

synthesized Ligases (synthases) (ligase)
