Diastase
Diastase is a group of enzymes that catalyze the breakdown of starch into maltose. These enzymes are produced by plants, animals, and microorganisms. Diastase was the first enzyme discovered and was named by Anselme Payen in 1833. The term "diastase" comes from the Greek word "diastasis," meaning "separation."
Types of Diastase[edit | edit source]
There are several types of diastase, including:
- Alpha-amylase: This enzyme breaks down long-chain carbohydrates, such as starch, into smaller sugar units like maltose and glucose. It is found in human saliva and pancreatic juice.
- Beta-amylase: This enzyme is found in plants, bacteria, and fungi. It breaks down starch into maltose units.
- Gamma-amylase: This enzyme further breaks down maltose into glucose units.
Function[edit | edit source]
Diastase plays a crucial role in the digestive system by breaking down complex carbohydrates into simpler sugars, which can be easily absorbed by the body. In plants, diastase helps in the conversion of stored starches into sugars during seed germination.
Applications[edit | edit source]
Diastase has various applications in different industries:
- In the food industry, diastase is used in the production of beer, whiskey, and other alcoholic beverages to break down starches into fermentable sugars.
- In the pharmaceutical industry, diastase is used as a digestive aid to help individuals with digestive disorders.
- In the textile industry, diastase is used to remove starch from fabrics.
History[edit | edit source]
The discovery of diastase marked a significant milestone in the field of biochemistry. Anselme Payen, a French chemist, discovered diastase in 1833 while studying the process of starch conversion in barley. This discovery laid the foundation for the study of enzymes and their role in biological processes.
