Enzymes are macromolecular biological catalysts. They accelerate chemical reactions.
The two industrially important enzymes are amylases and lipase.
Amylase is an enzyme that catalyses the hydrolysis of starch into sugars. Amylase is present in the saliva of humans and some other mammals, where it begins the chemical process of digestion. They are important industrially in brewing beer and liquor made from sugars i.e., fermentation, also used in breadmaking in industry.
Lipase is an enzyme that catalyzes the hydrolysis of fats (lipids). Lipase is used industrially in the preparation of yoghurt and cheese fermentation. food and baking industry.
