1. By substrate name
Enzymes are named by adding ase to the end of the substrate name.
(i) Sucrose + ase = Sucrase
(ii) Urea + ase = Urease
(iii) Tyrosine + ase = Tyrosinase
(iv) Protein + ase = Protease
(v) Pectin + ase = Pectinase
(vi) Lipid + ase = Lipase
(vii) Amylose + ase = Amylase
(viii) Arginine + ase = Arginase
2. According to the name of the reaction
Enzymes are named after the reaction that the enzyme affects. Enzymes are named by adding ase to the end of the reaction name. (i) Hydrolysis + ase = Hydrolase
(ii) Oxidation + ase = Oxidase
(iii) Epimarism + ase = Epimarase
(iv) Transferation + ase = Transferase
(v) Reduction + ase = Reductase
(vi) Isomerism + ase = Isomerase
(vii) Phosphorylation + ase = Phophorylase
(viii) Polymerism + ase = Polymerase
(ix) Carboxylation + ase = Carboxylase
(x) Alcohol dehydration + ase = Alchohol dehydrogenase
(xi) Cytochrome oxidetion + ase = Cytochrome oxidase
(xii) Nitrate reduction + ase = Nitratereductase
3. Name the substrate and reactant
Some enzyme names consist of two parts. One part is by the name of the substrate and the other part is by the name of the reactant.
(i) Hexose + Kinase = Hexokinase
(ii) Fructose 6 phosphate + Kiase = Phosphofructokinase
(iii) Phosphoglyceric acid + Mutase = Phosphoglyceromutase
(iv) Glucose 6 phosphate + Isomerism = Phosphogluco-isomerase
(v) Pyruvic acid + Kinase = Pyruvic acid kinase
(vi) Pyruvic acid + Carboxilation = Pyruvic carboxilase
(vii) Malic acid + Dehydrogenase = Malic dehydrogenase
