Reductase
Reductase
Reductase (pronunciation: /rɪˈdʌk.teɪs/) is a type of enzyme that catalyzes the chemical reaction of reduction, a process that involves the gain of electrons.
Etymology
The term "reductase" is derived from the Latin word reducere, meaning "to lead back", and the suffix -ase, which is used in the nomenclature of enzymes.
Function
Reductases play a crucial role in the body's metabolism. They are involved in various metabolic processes, including the synthesis of cholesterol, steroids, and fatty acids. They also participate in the detoxification of harmful substances in the body.
Types of Reductases
There are several types of reductases, each with a specific function. Some of the most common ones include:
- Nitrate reductase: This enzyme is involved in the process of nitrogen cycling in the environment.
- Methionine synthase reductase: This enzyme plays a role in the regeneration of methionine from homocysteine.
- 5-alpha reductase: This enzyme is involved in the conversion of testosterone into dihydrotestosterone.
Related Terms
