When we hear the term “radicals,” it might invoke thoughts of rebellious individuals or revolutionary movements.
However, in the scientific context, radicals refer to a fascinating and essential group of chemical species with profound implications for various fields.
What are Radicals?
In chemistry, radicals are atoms, molecules, or ions that contain one or more unpaired electrons, making them highly reactive and chemically unstable.
The unpaired electron is the key to their reactivity, as it seeks to pair with another electron, making radicals extremely reactive and capable of initiating chain reactions.
Types of Radicals
Radicals can be classified into different categories based on their origin and behavior. Some common types include:
Organic Radicals: Formed from organic molecules, these radicals play a significant role in various biological processes, including enzymatic reactions and cellular signaling.
Free Radicals: These are the most common radicals that arise from the splitting of chemical bonds due to energy input, such as heat or light.
Reactive Oxygen Species (ROS): ROS are a subset of radicals that involve oxygen molecules.
